Question

What are stomata? What is the role of stomata in photosynthesis? Explain the

opening and closing of stomata through diagram.​

Answer 1

Answer:

In botany, a stoma, also called a stomate is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.

The main functions of stomata are: Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding. ... Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.

The opening and closing depends upon the turgor pressure in the guard cells. The swelling of guard cells due to absorption of water causes opening of stomatal pores while shrinking of guard cells closes the pores. Opening and closing of stomata occurs due to turgor changes in guard cells.
