CAIE IGCSE Biology 16.3.8 Environmental conditions that affect
Practise identifying water, oxygen and suitable temperature as germination requirements, then explaining their roles in seed growth.
How this is tested
- state water, oxygen and suitable temperature as conditions required for seed germination
- explain oxygen as needed for aerobic respiration and energy release during germination
- interpret seed investigations where missing water, oxygen or heat prevents germination
