Question
What is the role of epidermis in plants?
Answer
The roles of the epidermis in plants are:
Protection: It protects the internal tissues from mechanical injury and invasion by parasitic fungi.
Prevents Water Loss: It forms a water-resistant layer (cuticle) on the outer surface to prevent the loss of water.
Gas Exchange: It contains small pores called stomata that allow the exchange of gases (oxygen and carbon dioxide).
Water Absorption: In roots, the epidermal cells have hair-like projections (root hairs) that increase the surface area for absorption of water.
