How do the Guard cells Regulate Opening and Closing of Stomatal Pores

- by Jaishree Gorane - 8 Comments.

Guard cells surround the stomata on the underside of leaves and regulate the gas exchange necessary for photosynthesis. They change shape to open and close the tiny pores. The stomata close when it is dark or the water level is low, while they open when there is plenty of light and water. Two theories, the potassium ion concentration theory and the sugar concentration theory, explain how the guard cells regulate the opening and closing of the stomata pores.
