In CAM (Crassulacean Acid Metabolism) plants, stomata open during dark and remain closed during the day. transpiration synonyms, transpiration pronunciation, transpiration translation, English dictionary definition of transpiration. Each stoma is surrounded by a pair of specialized, kidney shaped cells called guard cells, which possess chlorophyll and regulate the opening and closing of stomata. Stomatal Transpiration: Water vapour diffuses out through minute pore (stomata) present in soft aerial part of plant is known as Stomatal Transpiration. 9. The stomata are apertures in the epidermis, each bounded by two guard cells. In CAM photosynthesis, stomata remain closed during the day but open at night to absorb carbon dioxide, which is then stored in the vacuoles as malate. | Meaning, pronunciation, translations and examples Stomata (singular stoma) are gaps, mostly on the underside of leaves for gas exchange.
