See the plansGenetics: Unit Map and Reading Order
What the Genetics unit covers, how many questions it carries, and the order to read its five chapter notes in.
Botany Rapid Revision — Cycles, Pigments & Pathways
Photosynthesis and respiration accounting, plant hormones, life-cycle patterns and the classification characters that carry the 40-mark Botany block.
Carbohydrates, Lipids and Minerals: Sugars, Fats and What Soil Supplies
Sort sugars by size, linkage and reducing power, tell starch from cellulose from chitin, classify lipids and fatty acids, and match each plant mineral to its role and deficiency symptom.
Proteins and Enzymes: Folding, Catalysis and Inhibition
Build a protein from amino acids up to quaternary structure, classify proteins by shape and composition, name the enzyme classes, and predict how temperature, pH, substrate and inhibitors change the rate.
