Covers eukaryotic and prokaryotic cell structure, specialised cells and differentiation, the cell cycle and mitosis, stem cells, diffusion, osmosis and active transport, and microscopy and magnification, with the required practicals and exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.2 Organisation. Covers the levels of organisation, enzymes and the digestive system, the heart, blood vessels and lungs, blood, plant tissues with xylem, phloem and transpiration, and health, non-communicable disease and cancer, with the required practicals and exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.3 Infection and response. Covers the four types of pathogen and the diseases they cause, how pathogens spread and are controlled, the body's non-specific and immune defences, vaccination, antibiotics and drug development, and monoclonal antibodies, with the exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.4 Bioenergetics. Covers photosynthesis as an endothermic reaction, the limiting factors and their use in greenhouses, the inverse square law, aerobic and anaerobic respiration, and the body's response to exercise including oxygen debt, with the required practical and exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.5 Homeostasis and response. Covers the principles of homeostasis and control systems, the nervous system and reflexes, hormonal coordination and the endocrine system, the control of blood glucose and diabetes, and the hormones of human reproduction and fertility, with the required practical and exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.6 Inheritance, variation and evolution. Covers sexual and asexual reproduction and meiosis, DNA and the genome, genetic inheritance with Punnett squares and inherited disorders, variation and evolution by natural selection, selective breeding and genetic engineering, and classification, with the exam patterns AQA repeats.

A deep-dive AQA GCSE Biology guide to module 4.7 Ecology. Covers adaptations and competition with abiotic and biotic factors, the organisation of an ecosystem with food chains and the carbon and water cycles, biodiversity and human impact, and trophic levels with biomass transfer and sustainable food production, with the required practical and exam patterns AQA repeats.
