Explain different regions of root with neat labelled diagram.

Explanation

The tip of the root is covered by Thimble like structure called root cap which protect the root apex. A few m.m above the root cap, meristematic zone is present which consists of small, thin walled cells with dense protoplasm. These cells divided repeatedly. The cells proximal to this zone undergo rapid elongation and enlargement and are responsible for growth of the root in length. This region is called elongation region. The cells of the elongation zone gradually differentiate and mature so called maturation zone. From this zone, some of the epidermal cells form very thin and delicate thread like structures, called root hairs which help in absorption of water and Minerals from the soil.
