Factors affecting transpiration
Biology · Secondary 4 · Medium · Factors affecting transpiration
Shrubs on a forest floor are suddenly exposed to strong sunlight after tall trees are removed. How will this affect the rate of transpiration in the shrubs, assuming water is available?
- It increases because more light causes stomata to open wider, so more water vapour is lost.
- It decreases because light causes all stomata to close completely.
- It stays the same because light intensity does not affect transpiration.
- It stops completely because roots no longer absorb any water.
