What is the Function of Stomata ?


  • Stomata are tiny pores found on the surface of plant leaves and stems. They are surrounded by guard cells that can open and close the pore to regulate the exchange of gasses between the plant and the air.They are usually located on the underside of leaves, but can also be found on other parts of the plant, such as stems and fruit.  
  • When the stomata are open, plants can take in carbon dioxide from the air for photosynthesis and release oxygen. When the stomata are closed, the plant can conserve water by reducing transpiration, the process of water evaporation through the leaves. Stomata are important for the survival and growth of plants, as they play a key role in photosynthesis, the process by which plants make their own food using energy from sunlight.

8 Important Functions of Stomata

  1. The most important function of stomata is to facilitate the exchange of gasses between the plant and atmosphere by closing and opening the pores in the leaves.
  2. Stomata removes oxygen and takes in carbon dioxide at the time of photosynthesis.
  3. Stomata helps in transpiration and removal of excess water in the form of water vapor.
  4. Stomata also limits the loss of water due to evaporation and assists in maintaining a healthy water level within the plant. 
  5. Stomata reduces the loss of water through evaporation by getting closed during the night, thus maintaining a healthy water ratio in the plant.
  6. Stomata also assists in the process of photosynthesis by facilitating in exchange of gasses and water evaporation . 
  7. Stomata also helps in keeping the moisture content developed by  closing or opening its pores in different weather conditions. 
  8. Stomata also helps to expel the excess water out from the leaves in the form of water vapor.
