The remaining 97-99.5% is lost by transpiration and guttation. The high humidity in the air pocket reduces the water potential gradient between the leaf air spaces and the exterior and therefore decreases the rate of transpiration. Xerophytes possess larger number of stomata than mesophytes. Each stoma remains surrounded by two kidneys or bean shaped epidermal cells the guard cells. Stomata frequency of trees and shrubs is higher than herbs. Night-time transpirational water loss is most likely the consequence of having respiratory CO2 escape at sufficiently high rates through stomata. The spongy mesophyll is full of air pockets (hence the name spongy) that allow \(\ce{CO2}\) to move into the leaf to the palisade mesophyll, as well as allowing oxygen to diffuse from the palisade mesophyll through the spongy mesophyll and out the stomata. The sunken stomata creates a small pocket of moist air. There are several canals that appear as large, open circles in the cross section of the leaf. Sunken stomata create a pocket of air that is protected from the airflow across the leaf and can aid in maintaining a higher moisture content. 2014 Sep;114(4):711-23. doi: 10.1093/aob/mct313.

How does transpiration play a role in the water cycle? Transpiration pull is especially important at night. Since stomata represent the main interface for gas exchange between the leaf interior and the atmosphere, it is generally believed that their morphological and architectural features represent adaptations to environmental factors that affect transpiration and photosynthesis. The trichomes help capture evaporating moisture and maintain a relatively humid environment around the stomata. The evolutionary relations of sunken, covered, and encrypted stomata to dry habitats in Proteaceae. Rolled leaves keep their stomata inside, slowing water loss in the same way as sunken stomata.

Answer Now and help others. Plants with sunken stomata often have fewer stomata in general than plants in moister environments. A little pocket of moist air is created by the sunken stomata. The direction in which a leaf is facing, the plant's water status, peculiarities in leaf morphology, leaf stomata count and dispersion also affect the rate at which water is lost from the plant body via transpiration. In moist environments, this is often necessary because the plants take in more water than is necessary for photosynthesis. How does vegetation slow and prevent sediment loss? (c) The wall of the guard cell surrounding the pore is thicken and inelastic due to rest of the walls are thin, elastic and semi-permeable. Stomata are found mostly in green parts of plants like leaves, young stem, fruits etc. Answer 3 (c) sunken stomata. Water moves from a high water potential to a low water potential . The rate of transpiration is very closely linked with the rate of evaporation from the leaf surface. I review recent ideas as to why stomata are hidden and test experimentally whether hidden stomata may behave differently from those not covered by epidermal structures and so are coupled more closely to the atmosphere. Structure of stomata: Stomata are found primarily in the bottom epidermis of leaves. Observe a prepared slide of a pine needle cross section. Transpiration decreases when water content of the leaves decreases due to insufficient absorption by the root. The upper epidermis is free from stomata and, instead, is coated by a thick cuticle.
