How do plants regulate water loss
WebJun 4, 2015 · To protect itself against water loss the leaf has a waxy cuticle blocking water loss but it still need these openings to exchange Oxygen and Carbon Dioxide with the environment that it needs for photosynthesis. To do this the leaf has specialized epidermal cells that surround the stoma called guard cells.
