Factors affecting transpiration
Biology · Secondary 3 · Hard · Factors affecting transpiration
A potted plant is placed in a room with very low humidity but given plenty of water. What will most likely happen to the rate of transpiration and why?
- It increases because the water vapour gradient between leaf and air is steeper
- It decreases because stomata close in low humidity
- It stays the same because humidity does not affect transpiration
- It stops because the air cannot hold more water vapour
