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. WebThe three adaptations in plants to reduce the transpiration are, 1. Sunken stomata: – The stomata may be sunken or covered by hairs. 2.

WebAug 27, 2024 · Sunken stomata, as in adelfa or Nerium oleander, also lessen the rate of transpiration by sheltering the boundary layer from wind movement. Likewise, the presence of dry epidermal hairs or pubescence on the leaf surfaces tends to lessen the rate of transpiration by acting as windbreaks.

WebMay 4, 2024 · As transpiration occurs, the air surrounding a leaf becomes increasingly humid, reducing the difference in water potential between the intercellular air spaces and the atmosphere and slowing transpiration. When a breeze is present, however, the humid air is carried away and replaced by drier air. WebXerophytes and epiphytes often have a thick covering of trichomes or of stomata that are sunken below the leaf’s surface. Trichomes are specialized hair-like epidermal cells that …

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 ...
