Answer 2

Answer:

Epidermal cells of the roots, whose function is water absorption, commonly bear long hair-like parts that greatly increase the total absorptive surface area.

In some plants like dessert plants, epidermis has a thick waxy coating of cutin (chemical substance with waterproof quality) on its surface which adds to its protective covering.
