Question Question 13
What is the role of epidermis in plants?
The primary role of epidermis in plants is protection. The entire surface of a plant has an outer covering epidermis. It protects all the parts of the plant. Epidermal cells on the aerial parts of the plant often secrete a waxy, water resistant layer on their outer surface. This aids in protection against:
- loss of water
- mechanical injury
- invasion by parasitic fungi
