Opening and closing of stomata experiment
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. WebTheory: Stomata are small openings found widely scattered on the epidermis of leaves and young stems. They are mostly found on the lower surface of a dicot leaf and on …
