JCE Biology study guide
JCE Biology · Work through your exam, one topic at a time.
The Junior Certificate Examination (JCE) Biology is a school-leaving qualification in Botswana, typically taken at the end of Junior Secondary education. It is designed for learners who have completed the three-year junior secondary science programme and wish to obtain a formal certification recognised for progression to senior secondary or vocational pathways. The JCE Biology study guide has 9 sections and about 2,999 words.
01Cell Biology and Cell Processes
Cell Biology and Cell Processes examines the building blocks of life: cell structure, specialised cells, microscopy, movement of substances and enzyme-controlled reactions. You must recognise organelles, explain their functions and apply transport ideas to unfamiliar situations.
314 words, about 2 min02Nutrition in Plants and Animals
Nutrition in Plants and Animals covers photosynthesis, leaf structure, mineral nutrition, human dentition, digestion, absorption and food tests. Expect questions on limiting factors, enzyme action and diet-related disease.
336 words, about 2 min03Transport
Transport examines how substances move within organisms: diffusion and osmosis, water uptake, transpiration, xylem and phloem, blood, the heart and blood vessels. You must link structure to function and interpret direction of flow.
340 words, about 2 min04Respiration and Excretion
Respiration and Excretion covers energy release from food, gas exchange, breathing, the kidney and removal of waste. Questions often compare aerobic and anaerobic pathways and trace urine formation.
334 words, about 2 min05Coordination, Response and Homeostasis
Coordination, Response and Homeostasis examines nervous and hormonal control, reflex actions, sense organs, plant tropisms and maintenance of a stable internal environment. A reflex arc: receptor → sensory neurone → relay neurone in the spinal cord → motor neurone → effector.
328 words, about 2 min06Reproduction, Growth and Development
Reproduction, Growth and Development covers asexual and sexual reproduction, flower structure, pollination, seed formation and germination, human reproduction, the menstrual cycle, pregnancy, growth and development. Asexual reproduction produces genetically identical offspring from one parent; sexual reproduction involves gametes and produces variation.
339 words, about 2 min07Genetics, Variation and Inheritance
Genetics, Variation and Inheritance examines chromosomes, genes, DNA, cell division, monohybrid inheritance, sex determination, mutation and sources of variation. Chromosomes are found in the nucleus and are made of DNA.
347 words, about 2 min08Ecology, Environment and Conservation
Ecology, Environment and Conservation examines ecosystems, food chains and webs, energy flow, nutrient cycling, populations, adaptations, biodiversity and human impact. A habitat is where an organism lives; a population is all organisms of one species in an area; a community is all populations; an ecosystem includes the community and its physical environment.
326 words, about 2 min09Health, Disease and Practical/Experimental Skills
This domain combines health and disease with practical and experimental skills. It tests pathogens, transmission, immunity, treatment, lifestyle diseases, and your ability to design, carry out and evaluate investigations.
