The true statement is (c) A large amount of water flows out from the guard cells.
- The diagram (attached below) shows closed stomata.
- The closing and opening of stomata (openings present in leaves for gaseous exchange) are controlled by specialized surrounding cells. These cells are called guard cells.
- Stomata can open when the guard cells take in water from the surroundings. This happens when guard cells actively take a lot of sugars inside them. The water then flows in through osmosis.
- Stomata get closed when a large amount of water flows out from the guard cells.
