Answer: The guard cells helps in opening and closing of Stomata with the help of movement of water..
Explanation:
Stomata are small pores present in the epidermis of leaves. They regulate the process of transpiration and gaseous exchange. The stomatal pore is enclosed between two bean-shaped guard cells. The inner walls of guard cells are thick, while the outer walls are thin.
When water flows into the guard cells , they swell up and the curved surface causes the stomata to open.
When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata.
