Explain the regions of the root with a diagram.

(N/A) The root tip is divided into several distinct regions:
$\rightarrow$ Root Cap: The root is covered at the apex by a thimble-like structure called the root cap. It protects the tender apex of the root as it makes its way through the soil.
$\rightarrow$ Region of Meristematic Activity: The cells of this region are very small,thin-walled,and have dense protoplasm. They divide repeatedly.
$\rightarrow$ Region of Elongation: The cells proximal to the meristematic region undergo rapid elongation and enlargement and are responsible for the growth of the root in length.
$\rightarrow$ Region of Maturation: The cells of the elongation zone gradually differentiate and mature. This zone,proximal to the region of elongation,is called the region of maturation. Some epidermal cells in this region form very fine and delicate,thread-like structures called root hairs.
