Question

What is the role of the epidermis in plants?

Answer 1

Hint: The outer layer of cover that covers the plants is the epidermis. It covers all the plant components, such as the plant's root, stem, leaves, flower, fruit, and seed. It consists of multiple layers of propodeum and its composition varies from one plant to another.

Complete answer: In botany, epidermis, the outermost, protoderm-derived layer of cells covering the plant's stem, root, leaf, flower, fruit, and seed sections. A protective shield against mechanical damage, water loss, and infection is provided by the epidermis and its waxy cuticle. Without any intercellular space, the Epidermis covers the entire surface of the plants. Some of the plants also have epidermal hair to stop the lack of plant water. Epidermal cells are water tolerant and therefore reduce water loss in the plant. To prevent insects from biting or harming the plants, it also stores some chemicals. Epidermal hairs are found in the roots to enhance water absorption in the soil. The waxy layer called cuticle is also supplied to Epidermis, which acts as the protective barrier in the desert plants by reducing water loss. It safeguards both the plant's internal organs and the underlying tissues. It secretes some of the metabolic compounds necessary for the growth of plants.

Note: The epidermis has tiny minute pores called stomata in the leaves and stems, which assist in the transpiration process. Transpiration means the removal of water from the surface of the plant. In the exchange of gases and water, stomata are beneficial. A pair of cells called guard cells surround these pores. In the opening and closure of stomata, these cells are used.
