Biology · Secondary 4 · Medium · Factors affecting transpiration
A potted plant is placed in a bright room. First, the air around the leaves is very humid. Later, a fan is switched on and the air becomes much drier.
What happens to the rate of transpiration when the air changes from humid to dry?
What happens to the rate of transpiration when the air changes from humid to dry?

- It decreases because the air temperature falls.
- It increases because the water vapour gradient becomes steeper.
- It does not change because light intensity is constant.
