Factors affecting transpiration
Biology · Secondary 3 · Hard · Factors affecting transpiration
A potted plant is placed in a room where the air becomes very dry because a fan is switched on. What will most likely happen to the rate of transpiration of the plant?
- It decreases because the stomata close in dry air.
- It stays the same because humidity does not affect transpiration.
- It increases because the water vapour gradient between leaf and air becomes steeper.
- It stops completely because water cannot evaporate into dry air.
