Definition of Stomata: The stomata are minute pores which occur in the epidermis of the plants. Xerophytes have sunken stomata to prevent water loss from the plant. This is an adaptation to check excessive transpiration in these plants. The upper epidermis is free from stomata and, instead, is coated by a thick cuticle. Name the types of nitrogenous bases present in the RNA. 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. Stomates or stomata (singular: stomate or stoma) are structures on the surfaces of plant leaves that allow gas exchange (transpiration, i.e., loss of water vapor, uptake of CO 2, and emission or uptake of O 2) between the interior of a leaf and the atmosphere. How are transpiration and evaporation related? Stomata close when the guard cells lose water and become flaccid. The stomata are located at the base of these pockets, called stomatal crypts. They possess waxy Observe a prepared slide of a pine needle cross section. A better understanding of this phenomenon may result from examining the interactions between leaf cuticle and stomata and from functional comparisons of sunken versus superficially positioned stomata, especially when transpiration is low, for example at night or during severe drought.
