Explain stomata and its function in plants.

Stomata are tiny pores present on the surface of the leaves. These pores are surrounded by 'guard cells'. Following are its function in plants:

The carbon dioxide required in the process of photosynthesis is made available by Stomata, through direct absorption from the air.

Stomata help Plants in absorption of mineral nutrients and water from the soil. Not all the water absorbed is utilized by the plant. The water evaporates through the stomata present on the surface of the leaves by the process of transpiration. The evaporation of water from leaves generates a suction pull which can pull water to great heights in the tall trees. Transpiration also cools the plant.
