What is the role of epidermis in plants?

The epidermis is the outermost protective layer of a plant. It covers leaves, stems, roots, flowers, and fruits, acting as a barrier between the plant and its environment.

Functions of the epidermis:

• Protects the plant from physical injury and pathogens.

• Reduces water loss through a waxy layer called the cuticle.

• Helps in gas exchange through tiny pores called stomata.

• Root epidermal cells form root hairs, which absorb water and minerals from the soil.

In simple terms, the epidermis acts like the plant's "skin," protecting it while helping with essential processes such as absorption and gas exchange.
