Explain how sunken stomata lower the rate of transpairation
Biology
ScanSolve AI Answer
Sunken stomata are located in pits or depressions on the leaf surface. These depressions trap a layer of humid air directly above the stomata. This trapped, humid air reduces the water potential gradient between the inside of the leaf and the external atmosphere. A smaller water potential gradient slows down the rate at which water vapor diffuses out of the leaf, thereby lowering the rate of transpiration.
