WebStomata, the pores on the leaf epidermis, facilitate gas exchange in plants. Plants balance their CO 2 demands and water losses through the adjustment of stomatal size, density, and modulation (opening and closing of stomata); however, adjustments to stomatal size and density are only possible during stomatal ontogeny. Consequently, stomatal size and …
WebThere are two theories that explain about the opening and closing of stomata. Sugar concentration theory. According to this theory, chloroplast in guard cell starts photosynthesis and produces sugar. It increases the osmotic pressure that draws in water from adjacent cells. Thus, guard cells become turgid and stomata open.
