The small pores present of leaf’s surface are called: asA) StomataB) CellsC) Chlorophyll D) Grains?

Question

Answer

Small pores present on the leaves of plants are called as stomata. Stomata are small pores, tiny openings found on young stems and the epidermis of leaves and are located on the upper and lower epidermis of leaves. Stomata are involved in the gas exchange process and also participate in the regulation of water movement through transpiration.  Therefore, the correct answer is option A.

Answer

Stomata are minute aperture structures on plants found typically on the outer leaf skin layer, also known as the epidermis. They consist of two specialized cells, called guard cells that surround a tiny pore called as stomata. It helps the plant in exchange of gasses and transpiration.
Therefore, the correct answer is option A.

Stomata

Answer

The small pores present on a leaf's surface are called stomata.

Stomata are essential structures found on the surface of leaves, stems, and other plant organs. They are responsible for the exchange of gases, such as carbon dioxide and oxygen, between the plant and its environment. Stomata play a crucial role in photosynthesis, respiration, and transpiration.

Function of Stomata:

1. Gaseous Exchange: Stomata allow the exchange of gases between the plant and its surroundings. During photosynthesis, stomata open to allow carbon dioxide to enter the leaf and oxygen to exit. In contrast, during respiration, stomata open to release oxygen and uptake carbon dioxide.

2. Transpiration: Stomata also facilitate transpiration, which is the loss of water vapor from plant tissues. When stomata open, water evaporates from the leaf's surface, creating a negative pressure that pulls water up through the plant's vascular system.

3. Regulation of Water Balance: Stomata play a crucial role in regulating the water balance of a plant. When the plant is experiencing water stress, such as during drought conditions, stomata close to reduce water loss through transpiration.

Structure of Stomata:

Stomata consist of two specialized cells called guard cells that surround a pore. These guard cells control the opening and closing of the stomatal pore, thereby regulating gas exchange and water loss. When the guard cells are turgid (swollen with water), the stomatal pore opens. Conversely, when the guard cells lose water and become flaccid, the stomatal pore closes.

Importance of Stomata:

1. Photosynthesis: Stomata are essential for the process of photosynthesis as they allow carbon dioxide to enter the leaf, which is a necessary raw material for photosynthetic reactions.

2. Respiration: Oxygen is released during photosynthesis and is an essential component of respiration. Stomata facilitate the exchange of oxygen between the plant and its environment.

3. Transpiration and Water Transport: Stomata play a vital role in the regulation of water loss through transpiration. They help in maintaining the water balance of a plant by controlling the opening and closing of the stomatal pore.

In conclusion, stomata are small pores present on the surface of a leaf that regulate gas exchange, transpiration, and water balance in plants. They are crucial for the process of photosynthesis and respiration, making them essential for the survival and growth of plants.
