Guard Cells Definition, Function, Structure of Stomata on Plants
WebThe 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. The stomata can open and close to: regulate transpiration; allow gas exchange; Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open ... WebAs stomata play a fundamental role in regulating plant water use and carbon gain, they present a key target for improving WUE. Here, we review how changes in stomatal developmental traits can affect plant WUE and also drought tolerance.
