What happens to the rate of transpiration when light intensity increases?
Show answer and explanation
Correct answer: It increases because stomata open and the leaf warms up.
Light triggers the opening of stomata for photosynthesis and increases the temperature of the leaf. Both factors lead to a higher rate of water vapor diffusion out of the plant.
