WebPlant stomata are an essential route for bacterial pathogens to entry inside host tissue and cause diseases. As an important defense mechanism, plant stomata can actively restrict bacterial invasion by dynamically regulating the opening, closing, and reopening of stomatal guard cells. Therefore, acc … 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. WebThe opening of stomata with increasing temperature was apparently independent of the stomatal response regulated by atmospheric humidity. At high plant water stress, the stomatal response was reversed, i.e., the stomata closed when temperature was gradually increased.
