Question

What are the functions of the stomata?

Answer 1

Stomata are tiny pores present mainly in the leaf epidermis. Stomata functions are:

1. They serve in exchange for respiratory gases (oxygen and carbon dioxide).

2. They help in transpiration. Transpiration is the process of loss of water that occurs mainly through stomata by movement of water from intercellular spaces of mesophyll cells with higher water potential to the outside air with lower water potential.
