WebDec 16, 2024 · Transpiration is controlled by the opening and closing of stomata in response to environmental cues. Stomata must open for photosynthesis and respiration, but when stomata are open, water vapor is lost to the external environment, increasing the … 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 ...

WebDec 9, 2024 · Why are sunken stomata useful? Sunken stomata are found sunken in the leaves. These stomata have developed as an adaptation for plants growing in water-scarce conditions. They protect the loss of water from the plants by preventing the escape of water vapor due to the air currents or transpiration. The small pit size hinders the escape of water. WebWhen stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between efficient …
WebCommon adaptations to reduce the rate of transpiration include: Thick waxy cuticle: The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature. ...
