Question

What is the role of stomata?

Answer 1

ANSWER:-

Role of stomata:

Stomata are very important structure of plants and supports their various life processes:

(1).Gaseous exchange take place through stomata:

CO2 is taken during the process of photosynthesis and O2 is released out. During respiration O2 is taken and CO2 is given out.

(2). Transpiration:

Bulk of transpiration takes place through stomata.

Significance of transpirtation:

• Transpiration creates a suction pressure transpiration pull in the leaves. It is responsible for the ascent of sap in plants.
• Transpiration also helps in absorption of water and dissolved minerals due to transpirtation pull.
• During transpiration heat of vaporization is taken from the leaves. Therefore, it causes a cooling effect or maintains the normal temperature of the plants.
• As it causes reduction in temperature it prevents the photo oxidation of chlorophyll.
• Transpiration facilitates water cycle in nature.
