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. Sunken, covered, and encrypted stomata have been anecdotally linked with dry climates and reduced transpiration and therefore have been used to infer dry palaeoclimates from fossils. Transpiration pull-water is lost from from stomata by evaporation-water molecules form hydrogen bonds (cohesion)-cohesion holds molecules together in a long chain or column -as water is lost from the leaves, water potential I'd lowered and column of water moves along the gradient The sunken stomata creates a small pocket of moist air. Transpiration increases on increasing number of stomata. Sunken stomata: Stomata are small pores present on the surface of leaves.
