what is the function of stomata

Stomata are tiny pores present mainly on the surface of leaves. They are surrounded by guard cells and help in important plant activities.

Functions of stomata

• Exchange of gases:
  Stomata allow carbon dioxide (CO2) to enter the plant for photosynthesis and release oxygen (O2) into the atmosphere.

• Transpiration:
  They help remove excess water from the plant in the form of water vapour.

• Regulation of water balance:
  Guard cells control the opening and closing of stomata to reduce water loss when needed.

Importance of stomata

• Essential for photosynthesis

• Helps in respiration of plants

• Maintains plant temperature through transpiration

Without stomata, plants would not be able to exchange gases properly or control water loss efficiently.
