Question

Which of these surround stomatal opening?​

Answer 1

Answer:

$\Huge\sf\underline\blue{Answer}$

Guard cell function

Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.

Answer 2

Answer:

Stomata are composed of two guard cells. These cells have walls that are thicker on the inner side than on the outer side. This unequal thickening of the paired guard cells causes the stomata to open when they take up water and close when they lose water.
