Transpiration Process. Similar to the sweat glands on your skin, plants have openings on their leaves that allow water to escape, called stomata (singular: stoma). Stomata are usually found on the underside of a leaf to reduce excess water loss, and they're surrounded by guard cells that open and close the pores.Though stomata release water, their main purpose is to exchange gases.imilar to the sweat glands on your skin, plants have openings on their leaves that allow water to escape, called stomata (singular: stoma).

Abstract. 1  As one of the earliest plant groups to evolve stomata, hornworts are key to understanding stomata origin and function. 2  Hornwort stomata are large and scattered on sporangia that grow from their bases and release spores at their tips. We present data from development and immunocytochemistry that identify a role for hornwort stomata that is correlated with sporangial and spore maturation. We measured guard cells across the genera with stomata to assess developmental changes in size and to analyze any correlation with genome size.
