Module 2 Foundations in biology - Cell structure, biological molecules, nucleic acids, enzymes, biological membranes, cell division, cell diversity and cellular organisation. Module 3 Exchange and transport - Structure and function of gas exchange and transport systems in a range of animals and in terrestrial plants. Module 4 Biodiversity, evolution and disease - The biodiversity of organisms, classification, measuring biodiversity, pathogens and the evolution of animal and plant defences. Module 5 Communication, homeostasis and energy - Nerves, hormones, the kidney, plant and animal responses, photosynthesis and respiration. Module 6 Genetics, evolution and ecosystems - Manipulation of genomes, variation and genetics, biotechnology, ecosystems and populations.
