What is stometa? Give its function,​

Answer 1

Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

Answer 2

What is Stomata :

Any of the very small holes in the surface of a leaf or the stem of a plant that allow gases to pass in and out.

(OR)

Stomata are the tiny openings present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis. They control by transpiration rate by opening and closing.

Functions of Stomata :

Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding.

• It helps in transpiration and removal of excess water in the form of water vapour.
• Stomatal closure at night prevents water from escaping through pores.
• It maintains the moisture balance according to weather by opening and closing.
• Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.

Hope it helps.......
