In many gymnosperms and xerophytic plants (plants growing in desert), the stomata are present embedded deeply in the leaves, so that they are not exposed to sunlight directly. How do sunken stomata reduce transpiration? Sunken stomata have the following benefits: - They trap moist air, which reduces diffusion and, in turn, lowers water loss - They aid in lowering the rate of transpiration.
