WebMar 7, 2024 · transpiration, in botany, a plant’s loss of water, mainly through the stomata of leaves. Stomatal openings are necessary to admit carbon dioxide to the leaf interior and to allow oxygen to escape during photosynthesis. Hence, transpiration is generally considered to be merely an unavoidable phenomenon that accompanies the real functions of the … WebPlants cannot continue to transpire without wilting if the soil is very dry because the water in the xylem that moves out through the leaves is not being replaced by the soil water. This condition causes the leaf to lose turgor or firmness, and the stomata to close. If this loss of turgor continues throughout the plant, the plant will wilt.
