WebDec 9, 2024 · Stomata of the rolled leaves will not be exposed to the wind, reducing the rate of transpiration further, reducing water loss. By reducing leaves to spines on some xerophytes, this greatly reduces the surface area of the leaf, which greatly reduces the amount of transpiration, helping assist in reducing water loss. WebPlants regulate the rate of transpiration by controlling the size of the stomatal apertures.
