How can plants change rates of transpiration?

Question

Quizplus · Accepted Answer

Plants can change the rates of transpiration by adjusting the size of stomata openings. Stomata are the tiny pores on the surface of the leaves that allow water vapor and gases to diffuse in and out of the plant. By adjusting the size of these openings, plants can control the amount of water lost through transpiration. When the stomata are open, water can escape more readily, whereas when they are closed, transpiration slows down.
