Question 1

Guard cells are kidney-shaped cells surrounding the stomata on the underside of leaves. These cellschange their shape according to the amount of water that exists within them. The more water within, themore swollen the guard cells are and the stomata open. When water is sparse the guard cells shrivel andclose the stomata. Recent evidence suggests that there are blue-light receptors on the plasma membranesurface of guard cells that are coupled to potassium (K+) ion channels. K+ ions are normally found in highconcentration outside guard cell membranes when the channels are closed.What mechanism may account for the fact that guard cells are usually open during the day and closed atnight?
