WebJun 8, 2024 · The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts. WebXerophytes are plants which can survive in dry or desert regions, i.e. with little water. Sunken stomata ensure less water loss, thus reduces the rate of transpiration. Hence, these are characteristically found in xerophytes. In order to reduce transpiration, a maximum number of stomata in a dorsiventral leaf are present on the lower surface ...
Describe and explain 3 typical adaptations of a xerophytic
WebSome plants possess stomata that are sunken into the leaf surface, dramatically increasing the boundary layer and slowing transpiration. Boundary layers increase as leaf size increases, reducing rates of transpiration as well. WebJun 15, 2024 · Tiny hairs (trichomes): Hairy leaves like those found on lamb’s ear and lavender shade the stomata to reduce transpiration (the release of water vapor from the plant leaves into the air) and protect the leaf surface from direct contact with hot, dry air. These hairs also trap water particles to be absorbed by the leaves. city around austin tx
