Control of transpiration is, however, strongly influenced by the water-vapor concentration of the atmosphere.
WebHow does the stomata affect gas exchange in the plant? The role of stomata The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are. In the light, the guard cells absorb water by osmosis , become turgid and the stoma opens. In the dark, the guard cells lose water, become flaccid ... WebFeb 2, 2016 · How do plants regulate transpiration and water loss?
