Includes comparisons of eukaryotic and prokaryotic cells, links between cell structures and functions, and how specialised cells adapt for specific roles. Covers how cells develop into tissues, organs and organ systems, plus required maths for converting units, using standard form, and calculating magnification and diffusion-related ratios. Also addresses cell cycle stages, chromosomes, mitosis and stem cell functions, applications, and risk-benefit evaluation.","AQA Biology Checklist   \nDouble Award  \nVIDEO  \nEXAM  \nQ&A  \nTopic 1.
