IB Biology C1.3.3 Oxygen as by-product
Practise tracing oxygen release in photosynthesis to the splitting of water, using MCQs, diagrams and short structured responses.
How this is tested
- state that oxygen released in photosynthesis comes from water, not CO2
- explain bubbles from aquatic plants as oxygen produced when water is split by light
- distinguish oxygen-producing groups such as algae and cyanobacteria from fungi
