Match pigments to their peaks, run the Z-scheme and both kinds of photophosphorylation, count the ATP and NADPH of the Calvin and C4 cycles, and explain photorespiration, limiting factors and bacterial photosynthesis.
Unit 7 carries 6 of the 40 botany marks; with four chapters sharing them, this one averages one and a half (MEC publishes weights by unit, not by chapter). The MEC scope line: Introduction and significance; Photosynthetic pigments; Photosystem I and II; Light-dependent reactions; Calvin–Benson cycle (C3); Hatch–Slack pathway (C4); Photorespiration; Factors affecting photosynthesis; Concept of bacterial photosynthesis. Three ways it is asked:
