BGCSE BSSE Biology 1428 study plan

Label the organelles of a plant and an animal cell from memory and state one function for each

Compare prokaryotic and eukaryotic cell structure in a written table of at least six features

Explain diffusion, osmosis and active transport and predict the direction of water movement across a membrane in three given scenarios

Describe the lock-and-key model of enzyme action and predict the effect of temperature and pH changes on reaction rate

Distinguish reducing sugars, non-reducing sugars, starch, proteins and lipids by the tests used to detect them

Break down a mixed meal into the nutrients present and name the enzyme, substrate and product for each digestion step

Trace the route of a food molecule from mouth to absorption in the ileum, naming each organ and its role

Compare the structure of the alveolus and the villus and link each feature to its function

Interpret a table of breathing-rate or lung-volume data and describe the trend shown

Explain how exercise changes breathing rate and heart rate in terms of gas exchange and respiration

Label the heart, its valves and the main vessels, and state the direction of blood flow through each chamber

Compare arteries, veins and capillaries in a table linking wall structure to function

Describe the composition of blood and give one function for each component

Explain how the kidney produces urine by filtration and selective reabsorption

Describe how negative feedback controls body temperature or blood glucose and apply it to one worked example

Define gene, allele, genotype and phenotype and use them correctly in written answers

Complete monohybrid crosses including sex-linked inheritance and predict phenotype ratios

Explain the difference between mitosis and meiosis and state where each occurs

Describe how a reflex arc works and name the receptor, coordinator and effector in two examples

Explain how hormones and nerves differ in speed, duration and mode of transmission

Label the human reproductive systems and describe the roles of gametes in fertilisation

Sequence the stages of the menstrual cycle and link each to the hormones controlling it

Describe how a food chain, food web and pyramid of numbers represent energy flow

Explain the carbon and nitrogen cycles and identify one human impact on each

Interpret a population data set and describe the effect of a named limiting factor

Explain natural selection using a named example and distinguish it from artificial selection

Use a dichotomous key to classify five organisms into their kingdoms

State the cause, transmission, symptom and prevention of three named diseases

Describe how to control variables and improve reliability in a practical investigation

Interpret a graph or table and evaluate the strength of the conclusion drawn

Retrieve the ten most frequently examined facts from each heavy domain without notes

Redo every question missed in weeks 1 to 6 and confirm each is now correct

Practise extended answers of six marks or more under timed conditions

Draw and label the six core diagrams from memory: cell, heart, kidney, alveolus, reflex arc and food web

Complete two full timed mock papers and record the score for each domain

Identify the two weakest domains from mock results and revise them to at least 80 percent accuracy

Practise command words such as describe, explain, compare and evaluate on ten sample questions

Confirm exam timing by completing one paper within the allowed time without notes
