Answer:
The opening and closing of stomata are controlled by the guard cells. 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.

hey mate here is your answer
Explanation:
The swelling of guard cells due to the absorption of water causes the opening of stomatal pores while shrinking of guard cells closes the pores.
Opening and closing of stomata occur due to turgor changes in guard cells. When guard cells are turgid, stomatal pore is open while in flaccid conditions, the stomatal aperture closes.
