Question

What are the functions of the stomata?

Answer 1

Functions of Stomata: 

Stomata are tiny pores present mainly on the surface of leaves. Their main functions are:

• Gas exchange: They allow carbon dioxide (CO₂) to enter for photosynthesis and oxygen (O₂) to exit as a by-product.
• Transpiration: They help in the loss of water vapor from leaves, which helps in cooling the plant and drawing water and minerals from roots.
• Regulation: Stomata can open and close to control water loss depending on environmental conditions.

Conclusion: Stomata play a vital role in photosynthesis, respiration, and transpiration.
