CAIE IGCSE Biology EXTENDED 8.3.7 Why wilting occurs
Practise explaining wilting from the balance between water uptake and transpiration, using plant diagrams and environmental conditions.
How this is tested
- explain wilting when transpiration exceeds water uptake and cells become flaccid
- suggest factors
- apply continuous water supply evidence to explain why a leafy shoot does not wilt
