- The outermost layer of cells is the epidermis. It is present in plants as well as animals. Trichomes are fine outgrowths on plant epidermis. They are of diverse structure and functions. Root hair is a thin hair-like growth of an epidermal cell of a plant root. It performs the important function of absorbing water and minerals from the soil.
- The epidermal tissue system is mainly involved in the protection of the plant from wear and tear, mechanical injury, invasion by parasitic fungi, etc.
- Conducting tissues of the plant are xylem and phloem and they conduct water and food respectively.
