How do plants regulate water loss

WebAnswer (1 of 4): The roll of water in plants is misunderstood severely. Please understand it varies between types of plants. In general the desert areas have plants that naturally just disappear to the root or such in dry times or are plants with green stems which often function as leaves and whi... WebMar 20, 2024 · Plants regulate the rate of transpiration by controlling the size of the stomatal apertures. More leaves (or spines, or other photosynthesizing organs) means a bigger surface area and more stomata for gaseous exchange. This will result in greater water loss. What are the structures for gas exchange in plants?
