How do sunken stomata reduce transpiration?

Open in App

Solution

A little pocket of moist air is created by the sunken stomata.
Because of the high humidity in the air pocket, the water potential gradient between the leaf air spaces and the exterior is reduced, and the rate of transpiration is reduced.
