Summary of Stomata

Stomata concept is summarised in the following points:

• When stomata are open, they allow carbon dioxide to enter the leaf which the plant then uses to produce glucose, and food through photosynthesis.
• At the same time oxygen, a byproduct of photosynthesis is released through the stomata into the atmosphere.
• At night when sunlight is not available, the rate of photosynthesis significantly decreases and the need for CO₂ intake is greatly reduced.
• Closing the stomata at night helps to conserve water by reducing transpiration which is the loss of water vapor. This is particularly important in arid environments where water conservation is essential for plant survival when the Sun rises guard cells open the stomata and photosynthesis continues.

The diagram of Stomata is a diagrammatical representation of a pore (stoma) or stomata found mainly on the underside of plant leaves in the epidermis, stems, and other organs that control the exchange of gases particularly carbon dioxide and oxygen between the plant and its environment. The Diagram of stomata is essential to understanding its internal workings like gaseous exchange, photosynthesis, and its functioning.

What is Stomata?

Stomata (singular: stoma) are tiny openings present mainly on the lower surface of leaves, stems, and other plant organs. Stomata are present on the upper leaf area also but the no is fewer. Stomata play an important role in the process of gas exchange in plants, allowing for the uptake of carbon dioxide (CO₂) needed for photosynthesis and the release of oxygen (O₂) produced during this process.

Each of the leaves will have thousands of these stomata and they’re scattered through the lower epidermis which is the layer of hypodermal tissue. Stomata help regulate the opening and closing of pores in leaves so that the gaseous exchange takes place easily in the atmosphere.
