Systematic A Level Biology Notes

These are full-syllabus revision notes for A-level Biology, written in plain, simple language. They begin with cell biology, covering light and electron microscopes, magnification and resolution, how specimens are prepared, rules for biological drawing, the cell theory, and how prokaryotic and eukaryotic cells compare. Later sections cover histology, classification, transport, the chemicals of life, nutrition, gaseous exchange, respiration, excretion, homeostasis, coordination, animal behaviour, support and movement, reproduction, genetics, ecology and evolution. Much of the material is set out as tables and point-form comparisons, which makes it useful for revision and exam preparation in S5 and S6.
