Question 1Cannabis laws, regulations, and compliance

Under Canada's Cannabis Act, what is the minimum legal age for purchasing recreational cannabis, unless a province or territory has set a higher one?

  1. 16 years
  2. 18 years Correct answer.
  3. 19 years
  4. 21 years

Explanation

The federal Cannabis Act sets the baseline minimum age at 18 years, and provinces and territories may raise it but not lower it. Most provinces have chosen 19, matching their alcohol age. The federal floor exists to prevent youth access while allowing regional variation.

Question 2Cannabis laws, regulations, and compliance

In Canada, which level of government is primarily responsible for licensing and regulating retail cannabis stores?

  1. Provincial and territorial governments Correct answer.
  2. Municipal police services
  3. The federal government through Health Canada
  4. The Canada Revenue Agency

Explanation

The federal Cannabis Act establishes national rules such as age limits, possession caps, and product safety, while provinces and territories design and administer retail distribution and sales models. Municipalities may add zoning and business licensing but do not hold the primary retail authority. This split is often described as federal framework plus provincial implementation.

Question 3Cannabis laws, regulations, and compliance

What is the maximum amount of dried cannabis an adult may legally possess in public under the federal Cannabis Act?

  1. 50 grams
  2. 100 grams
  3. 30 grams Correct answer.
  4. 10 grams

Explanation

The federal possession limit for adults in public is 30 grams of dried cannabis or its equivalent in other product classes. Provinces may impose stricter personal limits, but they cannot exceed the federal cap. Equivalent conversions apply to fresh cannabis, concentrates, and edibles.

Question 4Cannabis laws, regulations, and compliance

Which statement best describes the legal status of unlicensed cannabis sales in Canada?

  1. They are lawful only for small cash transactions
  2. They are permitted if the seller pays excise duty
  3. They are regulated only by municipal bylaws
  4. They are a criminal offence under the Cannabis Act Correct answer.

Explanation

Selling cannabis without the required federal or provincial authorization is an offence under the Cannabis Act and can carry serious penalties. Paying tax or holding a municipal business licence does not substitute for a cannabis sales authorization. The illicit market is a central enforcement target of the legal framework.

Question 5Cannabis laws, regulations, and compliance

Which federal agency administers licences for cannabis cultivation, processing, and sale to provincially authorized distributors?

  1. The Canadian Food Inspection Agency
  2. The RCMP
  3. The Competition Bureau
  4. Health Canada Correct answer.

Explanation

Health Canada administers the federal licensing regime for cultivators, processors, and sellers under the Cannabis Act and its regulations. It reviews security, Good Production Practices, and record-keeping before granting licences. Other agencies play enforcement or consumer-protection roles rather than licensing.

Question 6Cannabis laws, regulations, and compliance

What does a 'seed-to-sale' tracking system require licensed cannabis businesses to do?

  1. Track only products that exceed a value threshold
  2. Record data only when a regulator requests an audit
  3. Report only annual sales totals to the province
  4. Document each plant and product batch through the supply chain Correct answer.

Explanation

Seed-to-sale tracking requires licensees to record cannabis at each stage, from propagation through harvest, processing, packaging, and sale. This supports recalls, diversion detection, and compliance audits. Records must generally be maintained continuously rather than on request.

Question 7Cannabis laws, regulations, and compliance

What does 'cannabis equivalence' mean in Canadian cannabis regulation?

  1. A method for converting cannabis products into a common dried-cannabis weight Correct answer.
  2. A tax credit for licensed producers
  3. A rule allowing retailers to swap products of equal price
  4. A standard for measuring THC potency in edibles

Explanation

Equivalence converts products such as fresh cannabis, concentrates, and edibles into a dried-cannabis equivalent so possession limits can be applied consistently. For example, a set quantity of concentrate or edible corresponds to a defined amount of dried cannabis. This lets one limit cover very different product forms.

Question 8Cannabis laws, regulations, and compliance

Which of the following is a core record-keeping obligation for licensed cannabis retailers?

  1. Publishing customer names on a public register
  2. Retaining sales records for a defined period for inspection Correct answer.
  3. Reporting each customer's purchases to police
  4. Destroying receipts immediately after each sale

Explanation

Licensees must keep records such as sales, inventory, and receipts for the period specified in the regulations so regulators can audit compliance. Records support traceability and investigations. Publishing customer details or mass-reporting purchases is not a legal requirement and would raise privacy concerns.

Question 9Cannabis laws, regulations, and compliance

A licensed retailer wants to display cannabis products in its storefront window. Under the federal Cannabis Act, which principle applies to such promotion?

  1. Promotion is allowed if the product is under a price threshold
  2. Promotion must not be done in a manner that can be seen by young persons Correct answer.
  3. Promotion may be seen by young persons only if labelled
  4. Promotion is permitted anywhere adults are present

Explanation

The Cannabis Act restricts promotion, particularly where it could be seen by young persons, and prohibits appealing to youth. Storefront displays visible from outside may breach these rules depending on provincial rules and visibility. Retailers must therefore manage signage and window displays carefully.

Question 10Cannabis laws, regulations, and compliance

A customer at a licensed store shows an expired driver's licence as proof of age. What is the most compliant response?

  1. Refuse the sale and request valid identification Correct answer.
  2. Accept it and note the expiry in the log
  3. Accept it because it shows a birth date
  4. Accept it if the customer verbally confirms their age

Explanation

Retailers must verify age using valid, government-issued identification as defined by provincial rules. An expired document is generally not acceptable proof, and verbal confirmation does not satisfy the requirement. Refusing the sale protects the licensee from a youth-access violation.

Question 11Cannabis laws, regulations, and compliance

A producer ships packaged cannabis to a provincial distributor without the required excise stamp. What is the likely compliance consequence?

  1. The omission is permitted for small batches
  2. The shipment is treated as non-compliant and may be refused or subject to enforcement Correct answer.
  3. The stamp can be applied by the distributor at no risk
  4. Excise stamps are optional for dried flower

Explanation

Cannabis products intended for sale must carry the required excise stamp, and shipping unstamped product is a compliance breach. Regulators and distributors may refuse the shipment, and penalties can follow. The stamping duty rests with the producer before the product enters the regulated market.

Question 12Cannabis laws, regulations, and compliance

A licensed retailer wants to run a loyalty program giving points for each purchase. Which consideration is most relevant under federal promotion rules?

  1. Loyalty programs are allowed only for medical cannabis
  2. Loyalty programs are entirely prohibited
  3. The program must not induce the purchase of cannabis or appeal to youth Correct answer.
  4. Points may only be redeemed for non-cannabis items

Explanation

Inducements that encourage cannabis purchase are restricted under the promotion provisions, and any program must avoid appealing to young persons. A loyalty scheme that rewards cannabis purchases may be treated as a prohibited inducement. Retailers should obtain legal review before launching such programs.

Question 13Cannabis laws, regulations, and compliance

What is the purpose of Good Production Practices (GPP) requirements for licensed cannabis producers?

  1. To govern advertising spend limits
  2. To set the minimum age for consumers
  3. To determine retail pricing across provinces
  4. To set minimum standards for sanitation, quality, and product safety Correct answer.

Explanation

Good Production Practices establish baseline standards for facilities, sanitation, personnel, and quality control so cannabis is produced safely and consistently. They are a core part of federal licensing conditions. Pricing, advertising budgets, and consumer age are handled by other rules.

Question 14Cannabis laws, regulations, and compliance

A retailer discovers a labelling error on a product batch already on shelves. What is the most appropriate first compliance action?

  1. Reprint labels in-store and apply them over the originals
  2. Quarantine the batch and follow recall procedures Correct answer.
  3. Discount the product to speed up sales
  4. Continue selling until the batch is exhausted

Explanation

When a labelling defect is identified, the licensee should stop distribution, quarantine affected stock, and follow the applicable recall and notification process. In-store relabelling by a retailer is generally not permitted because labels are controlled by the licensed producer. Selling through the batch could expose consumers to misinformation.

Question 15Cannabis laws, regulations, and compliance

Which packaging requirement applies to recreational cannabis sold in Canada?

  1. Packaging must be transparent so the product is visible
  2. Packaging may show the brand mascot prominently
  3. Packaging must be plain and not appeal to youth Correct answer.
  4. Packaging may include cartoon characters if small

Explanation

Federal rules require plain, child-resistant packaging that does not appeal to young persons and limits branding elements. Cartoon characters and mascots are generally prohibited because they attract youth. Transparency and vivid branding conflict with these objectives.

Question 16Cannabis laws, regulations, and compliance

A province sets a public possession limit of 15 grams for adults. How does this interact with the federal 30-gram limit?

  1. The provincial limit is invalid because it conflicts with federal law
  2. The federal limit overrides and permits 30 grams
  3. The stricter provincial limit applies within that province Correct answer.
  4. Both limits apply only to medical patients

Explanation

Provinces may impose stricter personal possession limits than the federal cap, and the stricter rule governs within that jurisdiction. The federal 30-gram figure is a ceiling, not a guaranteed entitlement everywhere. Retailers and consumers must follow the local limit.

Question 17Cannabis laws, regulations, and compliance

Which activity requires a federal licence under the Cannabis Act?

  1. Discussing cannabis laws at a public seminar
  2. Selling cannabis seeds at a municipal farmers market without authorization
  3. Possessing 30 grams of dried cannabis for personal use
  4. Cultivating cannabis for commercial sale Correct answer.

Explanation

Commercial cultivation requires a federal licence from Health Canada, along with compliance with security and production standards. Personal possession within limits and public discussion do not require a licence. Unauthorized sale of seeds is itself unlawful rather than a licensable activity.

Question 18Cannabis laws, regulations, and compliance

A licensed producer wants to export cannabis to a foreign country. What must be confirmed first?

  1. That the product is packaged in the producer's brand colours
  2. That the foreign buyer pays in Canadian dollars
  3. That the shipment exceeds 100 kilograms
  4. That the destination country authorizes the import and Canadian permits are in place Correct answer.

Explanation

Cannabis exports require authorization from both the Canadian regulator and the destination country's legal framework. Canada permits exports only for medical or scientific purposes to jurisdictions that allow the import. Packaging style, shipment size, and currency are irrelevant to export legality.

Question 19Cannabis laws, regulations, and compliance

What is the main regulatory purpose of child-resistant packaging for cannabis products?

  1. To reduce accidental ingestion by children Correct answer.
  2. To lower production costs
  3. To make products harder to open for adults
  4. To comply with food labelling laws

Explanation

Child-resistant packaging is required to reduce the risk of accidental ingestion by young children, who may mistake cannabis edibles or other products for treats. The design must remain reasonably easy for adults to open. This is a public-health measure within the federal packaging rules.

Question 20Cannabis laws, regulations, and compliance

A retailer wants to sell cannabis-infused beverages alongside alcohol in the same licensed premises. Which statement best reflects typical provincial regulation?

  1. Combined sale is allowed if staff are trained
  2. Combined sale is generally restricted or prohibited by provincial rules Correct answer.
  3. Combined sale is allowed if the store pays a fee
  4. Combined sale is permitted only on weekends

Explanation

Provinces generally separate cannabis retail from alcohol sales to limit co-use and youth access, and many prohibit selling both in the same premises. Licensing frameworks may also restrict cross-promotion. Retailers must check the specific provincial rules before combining product categories.

Question 21Cannabis laws, regulations, and compliance

A customer asks a budtender for medical advice about treating a health condition with cannabis. What is the safest compliant response?

  1. Refer the customer to a health care professional Correct answer.
  2. Provide a treatment plan based on symptoms
  3. Recommend a specific strain and dose
  4. Guarantee the product will cure the condition

Explanation

Retail staff are not authorized to diagnose or prescribe, and doing so can breach health-profession and advertising rules. The compliant approach is to refer customers with medical questions to a physician, nurse practitioner, or pharmacist. General product information may be provided within the promotion limits.

Question 22Cannabis laws, regulations, and compliance

Which of the following best describes the federal limit on cannabis advertising in Canada?

  1. Advertising that could be seen by young persons or that promotes a brand is restricted Correct answer.
  2. Advertising is allowed if the product is low potency
  3. Advertising is permitted if it includes a health warning
  4. Advertising is unrestricted on social media

Explanation

Federal law restricts cannabis promotion, including brand promotion and any advertising that could be seen by young persons or that associates cannabis with a lifestyle. Informational promotion is allowed only in narrow circumstances. Potency and social media platforms do not create exemptions.

Question 23Cannabis laws, regulations, and compliance

A licensed producer is planning to sponsor a community music festival. Under federal promotion rules, what is the primary concern?

  1. Whether the festival is held outdoors
  2. Whether the producer's logo is small
  3. Whether the producer files a tax return for the sponsorship
  4. Whether the sponsorship could be considered an inducement or appeal to youth Correct answer.

Explanation

Sponsorships can constitute prohibited promotion if they associate cannabis with a lifestyle or event attractive to youth, or if they induce cannabis purchase. Producers must assess audience and messaging carefully. Tax treatment, venue type, and logo size do not resolve the promotion question.

Question 24Cannabis laws, regulations, and compliance

A provincial inspector finds that a retailer's inventory records do not match physical stock. What is the most likely regulatory significance?

  1. It is a minor issue with no compliance implications
  2. It automatically closes the store permanently
  3. It may indicate diversion or poor record-keeping and can trigger enforcement Correct answer.
  4. It matters only if the discrepancy exceeds 500 grams

Explanation

Inventory discrepancies can signal diversion of cannabis to the illicit market or failure to maintain required records, both of which are serious compliance issues. Regulators may investigate and impose sanctions. The significance is not limited to a fixed weight threshold.

Question 25Cannabis laws, regulations, and compliance

A producer wants to sell a new edible shaped like a cartoon animal. How should the compliance team evaluate this design?

  1. Approve it if sold only online
  2. Approve it because edibles are exempt from packaging rules
  3. Reject it because shapes appealing to youth are prohibited Correct answer.
  4. Approve it if the THC content is low

Explanation

Cannabis edibles must not be shaped or packaged in a way that appeals to young persons, and cartoon-animal shapes are a clear example of prohibited appeal. Potency and sales channel do not cure the design problem. Producers should redesign to a neutral shape before seeking approval.

Question 26Cannabis laws, regulations, and compliance

Under Canada's federal Cannabis Act, what is the maximum amount of dried cannabis an adult may possess in public at one time?

  1. 50 grams
  2. 30 grams Correct answer.
  3. 10 grams
  4. 100 grams

Explanation

The federal Cannabis Act sets a public possession limit of 30 grams of dried cannabis, or its equivalent, for adults. Provinces may lower this limit but cannot raise it above the federal ceiling. This baseline applies uniformly across the country unless a province has enacted a stricter cap.

Question 27Cannabis laws, regulations, and compliance

Which federal body is primarily responsible for administering licences for cannabis cultivation, processing, and sale under the Cannabis Act?

  1. The Canada Revenue Agency
  2. The RCMP
  3. Health Canada Correct answer.
  4. The Canadian Food Inspection Agency

Explanation

Health Canada administers the federal cannabis licensing regime under the Cannabis Act and its regulations. It issues licences for cultivation, processing, testing, and sale, and conducts compliance and enforcement activities. Other agencies have supporting roles but do not issue these licences.

Question 28Cannabis laws, regulations, and compliance

Which minimum age does the federal Cannabis Act set for lawful purchase of recreational cannabis, while allowing provinces to set a higher age?

  1. 19 years
  2. 18 years Correct answer.
  3. 16 years
  4. 21 years

Explanation

The federal Cannabis Act sets 18 as the minimum age for recreational cannabis, and provinces may set a higher age. Most provinces have chosen 19, aligning with alcohol rules. The federal floor cannot be lowered by a province.

Question 29Cannabis laws, regulations, and compliance

Which statement best describes the federal rule on promoting cannabis products through testimonials or endorsements?

  1. Testimonials and endorsements are prohibited in cannabis promotion Correct answer.
  2. Testimonials are allowed only in print media
  3. Testimonials are allowed if the person is over 18
  4. Testimonials are allowed if approved by Health Canada

Explanation

The Cannabis Act prohibits promotion that could reasonably be believed to be a testimonial or endorsement of cannabis. This restriction applies regardless of medium or the age of the person giving the endorsement. It is part of the broader limits designed to prevent inducement to use cannabis.

Question 30Cannabis laws, regulations, and compliance

A licensed cultivator wants to hire a new employee who will handle cannabis plants directly. Which requirement most directly applies before the person begins work?

  1. The person must hold a provincial retail licence
  2. The person must complete a federal tax registration
  3. The person must obtain a security clearance from Health Canada Correct answer.
  4. The person must be a shareholder of the licensed producer

Explanation

Individuals who work with cannabis at a licensed site, particularly those with access to plants or finished product, generally require a security clearance from Health Canada. This screening addresses risks of diversion and organized crime infiltration. Retail licensing and tax registration are separate matters.

Question 31Cannabis laws, regulations, and compliance

A licensed producer wants to sell cannabis oil in a container that resembles a juice box. What is the most relevant compliance concern?

  1. The packaging may be considered appealing to youth and therefore prohibited Correct answer.
  2. The packaging must be approved by the provincial liquor board
  3. The packaging must include a nutrition facts panel
  4. The packaging must be clear glass

Explanation

Federal rules prohibit cannabis packaging that is appealing to youth, including designs that resemble familiar products marketed to children. A juice-box style container could raise concerns under these restrictions. Producers should assess the design against packaging and labelling requirements before sale.

Question 32Cannabis laws, regulations, and compliance

A licensed retailer receives a shipment of dried cannabis and notices the excise stamp is missing on some units. What is the most compliant immediate action?

  1. Quarantine the affected units and report the discrepancy before selling them Correct answer.
  2. Sell the units at a discount to clear inventory
  3. Apply a store-generated stamp to the units
  4. Return the units to the shelf and note the issue later

Explanation

Cannabis products for sale must bear the required excise stamp, and missing stamps indicate a compliance failure. The retailer should segregate the affected product and report the issue rather than selling it. Selling unstamped product can expose the retailer to enforcement action.

Question 33Cannabis laws, regulations, and compliance

A licensed producer wants to conduct a promotional event where attendees can sample cannabis products. Which consideration is most important under federal promotion rules?

  1. Promotion that could induce cannabis use is restricted, and sampling raises significant concerns Correct answer.
  2. Sampling is allowed if the producer holds a processing licence
  3. Sampling is allowed if the event is private
  4. Sampling is permitted if attendees are over 19

Explanation

Federal promotion rules restrict activities that could encourage cannabis use, and sampling events raise serious concerns under these provisions. Age verification alone does not resolve the prohibition on inducement. Producers should obtain legal advice and consider alternative compliant approaches.

Question 34Cannabis laws, regulations, and compliance

A province announces a new rule requiring cannabis stores to close by 9 p.m. How does this interact with federal law?

  1. The rule is invalid because only the federal government regulates retail hours
  2. Provinces may impose additional restrictions on retail hours within their jurisdiction Correct answer.
  3. The rule applies only to online sales
  4. The rule requires Health Canada approval before taking effect

Explanation

Provinces have authority over retail distribution and sale within their borders, including operating hours and store rules, provided they do not conflict with federal law. Federal law sets national requirements but does not preclude stricter provincial retail rules. Retailers must follow the stricter applicable provincial requirements.

Question 35Cannabis laws, regulations, and compliance

A licensed retailer discovers that a customer purchased cannabis using a fake identification card. What is the most appropriate compliance response?

  1. Refund the purchase and take no further action
  2. Ignore the incident because the sale is complete
  3. Document the incident and review age-verification procedures Correct answer.
  4. Report the customer to Health Canada directly

Explanation

Retailers are expected to maintain robust age-verification practices and to document incidents that suggest failures. Reviewing procedures and training staff helps prevent recurrence and demonstrates due diligence. Reporting obligations typically run to provincial regulators rather than directly to Health Canada for a single retail sale.

Question 36Cannabis laws, regulations, and compliance

Which federal regulation governs the quality and production standards that licensed cannabis producers must follow?

  1. The Cannabis Regulations, including Good Production Practices Correct answer.
  2. The Food and Drug Regulations
  3. The Controlled Drugs and Substances Act
  4. The Excise Act, 2001

Explanation

The Cannabis Regulations set out Good Production Practices and related quality requirements for licensed producers. These cover sanitation, pest control, and record-keeping that support product safety. Other statutes address food, excise, or controlled substances but not cannabis production standards.

Question 37Cannabis laws, regulations, and compliance

A licensed producer wants to sell cannabis products online directly to consumers in a province that permits online sales only through its own provincial store. What is the most compliant approach?

  1. Sell directly to consumers because federal licences permit online sales
  2. Sell only through the provincial channel as required by that province Correct answer.
  3. Sell directly to consumers but only within the province
  4. Sell directly to consumers with a disclaimer

Explanation

Provinces determine the distribution model for recreational cannabis within their borders, including whether direct-to-consumer online sales are permitted. A federal licence does not override provincial distribution rules. The producer should route sales through the authorized provincial channel.

Question 38Cannabis laws, regulations, and compliance

A licensed processor is designing a new cannabis extract product and wants to confirm allowable ingredients. Which source should the compliance team consult first?

  1. The Cannabis Regulations and Health Canada guidance on permitted ingredients Correct answer.
  2. Municipal zoning bylaws
  3. The Excise Act, 2001
  4. Provincial retail pricing schedules

Explanation

The Cannabis Regulations and associated Health Canada guidance specify permitted ingredients and restrictions for cannabis products. Compliance teams should verify formulations against these federal sources before production. Pricing schedules, excise rules, and zoning do not define allowable ingredients.

Question 39Cannabis laws, regulations, and compliance

A licensed producer is considering exporting cannabis to a country where cannabis is legal. What must the producer confirm before proceeding?

  1. That the destination country has legalized recreational use
  2. That the producer holds a provincial retail licence
  3. That the destination country has authorized the import and the required permits are in place Correct answer.
  4. That the shipment is under 30 grams

Explanation

Exporting cannabis requires authorization from the destination country and appropriate permits under Canadian rules. Legalization in the destination country alone is insufficient without import authorization. The producer must also comply with Health Canada export requirements.

Question 40Cannabis laws, regulations, and compliance

A licensed retailer wants to offer a 'buy two, get one free' promotion on cannabis products. Which analysis best reflects federal promotion rules?

  1. The promotion may constitute inducement to use cannabis and is likely restricted Correct answer.
  2. The promotion is permitted because it is a volume discount
  3. The promotion is permitted only in provinces that allow it
  4. The promotion is permitted if the free item is low potency

Explanation

Federal promotion rules restrict inducements that could encourage cannabis use, and free-product offers raise significant concerns under these provisions. Volume discounts and potency do not exempt a promotion from the rules. Retailers should seek legal review before implementing such offers.

Question 41Cannabis plant biology, genetics, and cultivation

In cannabis, which structure is the primary site of cannabinoid biosynthesis?

  1. Pollen sacs of male flowers
  2. Glandular trichomes on female flowers Correct answer.
  3. Xylem vessels in the main stem
  4. Root hairs of the taproot

Explanation

Cannabinoids such as THC and CBD accumulate mainly in the resin secreted by glandular trichomes, which are dense on the bracts and small leaves surrounding female flowers. Other plant tissues contain far lower concentrations.

Question 42Cannabis plant biology, genetics, and cultivation

Cannabis is best described by which photoperiodic classification?

  1. A long-day plant that flowers as days lengthen
  2. A biennial that flowers only after winter vernalization
  3. A day-neutral plant that flowers regardless of night length
  4. A short-day plant that flowers as nights lengthen Correct answer.

Explanation

Cannabis initiates flowering when the dark period exceeds a critical length, so indoor growers typically switch to a 12-hour light schedule. Long nights trigger the transition from vegetative growth to flowering.

Question 43Cannabis plant biology, genetics, and cultivation

Which pigment primarily mediates the photoperiodic flowering response in cannabis?

  1. Chlorophyll b
  2. Carotene
  3. Anthocyanin
  4. Phytochrome Correct answer.

Explanation

Phytochromes are photoreversible pigments that measure the length of the dark period and signal flowering time. Chlorophyll and carotenoid pigments serve light harvesting, while anthocyanins are accessory pigments.

Question 44Cannabis plant biology, genetics, and cultivation

A grower wants to keep a mother plant in continuous vegetative growth indoors. Which light schedule best accomplishes this?

  1. 10 hours light and 14 hours dark
  2. 18 hours light and 6 hours dark Correct answer.
  3. 8 hours light and 16 hours dark
  4. 12 hours light and 12 hours dark

Explanation

Long days with short nights keep cannabis in the vegetative phase because the dark period stays below the critical length. Schedules with long uninterrupted nights promote flowering instead.

Question 45Cannabis plant biology, genetics, and cultivation

Which cannabis plant type is typically shortest and most compact, suited to short growing seasons?

  1. Hemp
  2. Indica
  3. Ruderalis Correct answer.
  4. Sativa

Explanation

Cannabis ruderalis originates in northern latitudes and is small, fast-maturing, and often autoflowering. It is frequently used in breeding to introduce autoflowering traits.

Question 46Cannabis plant biology, genetics, and cultivation

What is the primary function of the cotyledons during cannabis seedling establishment?

  1. Producing resin to deter herbivores
  2. Anchoring the seedling against wind
  3. Storing and supplying nutrients until true leaves photosynthesize Correct answer.
  4. Absorbing nitrogen from soil particles

Explanation

Cotyledons are the seed leaves that store reserves and supply the emerging seedling before it can photosynthesize on its own. Once true leaves develop, the cotyledons often yellow and drop.

Question 47Cannabis plant biology, genetics, and cultivation

Which environmental factor most directly drives transpiration rate in a cannabis canopy?

  1. Number of cotyledons
  2. Vapor pressure deficit between leaf and air Correct answer.
  3. Seed coat thickness
  4. Soil cation exchange capacity

Explanation

Transpiration is driven by the vapor pressure gradient between the moist interior of the leaf and the surrounding air, often expressed as vapor pressure deficit. Higher VPD increases water loss through stomata.

Question 48Cannabis plant biology, genetics, and cultivation

Which macronutrient is most associated with vigorous vegetative growth and dark green leaf color in cannabis?

  1. Nitrogen Correct answer.
  2. Potassium
  3. Phosphorus
  4. Calcium

Explanation

Nitrogen is a component of chlorophyll and amino acids, so adequate supply supports leafy vegetative growth and green coloration. Deficiency typically causes pale lower leaves.

Question 49Cannabis plant biology, genetics, and cultivation

A breeder crosses a true-breeding high-THC plant with a true-breeding low-THC hemp plant and observes intermediate THC in the F1. This pattern is most consistent with which inheritance mode?

  1. Maternal inheritance
  2. Incomplete dominance at a major locus Correct answer.
  3. Sex-linked inheritance
  4. Complete dominance at a major locus

Explanation

An intermediate F1 phenotype indicates incomplete dominance, where the heterozygote expresses a blend of the parental traits. Complete dominance would yield an F1 resembling one parent.

Question 50Cannabis plant biology, genetics, and cultivation

In cannabis, the genes underlying the THC and CBD synthase pathway are best described as:

  1. Polygenic traits with no major-effect locus
  2. Mitochondrial genes inherited only from the seed parent
  3. Independently assorting loci on different chromosomes
  4. Closely linked alleles at a single locus Correct answer.

Explanation

The functional and inactive forms of the THCA synthase gene behave as alleles at one locus, so a plant usually produces mainly THC, mainly CBD, or a mix. This linkage explains why THC and CBD levels are inversely related in many cultivars.
