Answer:
1- Its main function is the exchange of gases by opening and closing the pores in the leaves.
2- It helps in removing water from the leaves.
3- It takes carbon dioxide and gives out oxygen during the process of photosynthesis and helps in regulating water movement through transpiration.
Explanation:
Functions of the stomata
1.They allow the exchange of gases (CO2 and O2) with the atmosphere.
2.Evaporation of water from the leaf surface occurs through the stomata. Thus, the stomata help in the process of transpiration.
3.Based on the climatic conditions, it closes or opens its pores to maintain the moisture balance.
4.Allows the intake of carbon dioxide and give out oxygen during the process of photosynthesis.
5.Stomata remain open during the day and closed at night. This closure at night prevents water from escaping through open pores.
