Explain in brief the role of the epidermis in plants.
The epidermis plays a very important role in plants. It acts as a barrier between the plant and the outside environment. As given in the NCERT Class 9 Science Chapter 6 Notes Tissues, it also depends on the plant to prevent water loss and regulate gas exchange. The epidermis also secretes various metabolic chemicals and helps in the absorption of water and mineral nutrients in the roots.
