Biology · Secondary 4 · Medium · Factors affecting transpiration
A plant is placed in a room where the air is very dry but light intensity and temperature remain constant. What will happen to the rate of transpiration and why?
- It decreases because the stomata close in dry air
- It stays the same because light intensity is unchanged
- It increases because the water vapour gradient becomes steeper
- It decreases because less water is absorbed by the roots
