$\rightarrow$ 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.

$\rightarrow$ vRegion of Meristematic Activity : The cells of this region are very small, thin-walled and with dense protoplasm. They divide repeatedly.

$\rightarrow$ Region of elongation : The cells proximal to this region undergo rapid elongation and enlargement and are responsible for the growth of the root in length.

$\rightarrow$ Root hair : Some epidermal cells form very fine and delicate, thread-like structures called root hairs.

$\rightarrow$ Region of maturation : The cells of the elongation zone gradually differentiate and mature This zone, proximal to region of elongation is called the region of maturation.
