Question

mention the functions of open stomatal pore and closed stomatal pore ?

​

Answer 1

The functions of the open and closed stomatal pores can be described as follows:

Explanation:

• When there is excess of water in the plant cells, the guard cells open the stomatal pores so that water can be lost by the pores.

• When there is less water present in the plant cells, the guard cells become flaccid and close the stomatal pores. As a result, less water is lost from the plant be evaporation.

• Hence, the opening and closing of the stomatal pores is an important phenomenon to maintain the turgidity of a plant.
