Question

How do guard cells regulate the opening and closing of the

stomata?​

Answer 1

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.

Answer 2

Answer:

when water enter in the guard cells, they swells up and the stomatal pore closes .

when water come out of the cells ,they contract and the stomatal pore open।
