How root hairs and microvilli are analogous structures. Concept introduction : Analogous structures are those structures that perform the same function but are unrelated to each other. The analogous structure arises due to the convergent evolution. Root hairs are extensions of the root epidermis, present predominantly on the growing roots of the plant. They are basically modified epidermal cells. They mainly function in water and minerals absorption from the soil. Root hairs have very short life span, but constitute about 90 percent of the total surface area of the roots. Microvilli are finger like projections present in the small intestine of humans and other animals. They greatly increase the total surface area for absorption of the nutrients. Hence, they share similarities with root hairs of plants.
