Factors affecting transpiration
Biology · Secondary 4 · Medium · Factors affecting transpiration
A student places a potted plant in a room and switches on a fan so that air blows across the leaves. Compared to before the fan was switched on, what will most likely happen to the rate of transpiration, and why?
- It decreases because air movement cools the leaf surface.
- It decreases because stomata close when air moves over the leaf.
- It increases because moving air removes water vapour around the leaf.
- It stays the same because air movement does not affect diffusion.
