Question

what is stomata ? give function.​

Answer 1

Explanation:

When a leaf is examined under the microscope, we can observe many tiny pores, which are collectively called stomata.

Stomata are the minute openings, generally found in the epidermis of leaves. They are typically found in plant leaves and can also be found in stems and other parts of plants. Stomata play an important role by permitting the movement of gases such as oxygen, carbon dioxide, and water vapour to diffuse between the interior and outer surface of the plant tissues.

Functions of Stomata

The main functions of stomata are:

Helps in the exchange of gases by opening and closing the pores in the leaves.

It helps to expel the excess water out from the leaves in the form of water vapour.

Based on the weather conditions, it closes or opens its pores to maintain the moisture balance.

Allow the uptake of carbon dioxide and to give out oxygen during the process of photosynthesis.

Stomata remain open during the day and closed at night. This closure prevents water from escaping through open pores

Stomata

Stomata are very small openings in membranes, particularly in plants, through which water and gas pass. An example of stomata are microscopic pores in leaves where plants release gases.

Functions of Stomata:

1》The main function of stomata is to open and close the pores in the leaves for an exchange of gases.

2》It allows the plant to take in carbon dioxide and give out oxygen for photosynthesis.

3》Based on the weather conditions, it closes or opens its pores to keep the moisture content developed.
