(N/A) The root tip is divided into three main regions based on the activity of the cells:
$1$. Region of Meristematic Activity: This is located a few millimeters above the root cap. The cells in this region are very small,thin-walled,and with dense protoplasm. They divide repeatedly.
$2$. Region of Elongation: This region is located just above the meristematic region. The cells here undergo rapid elongation and enlargement,which is responsible for the growth of the root in length.
$3$. Region of Maturation: This region is proximal to the elongation region. The cells in this zone gradually differentiate and mature. Some of the epidermal cells in this region form very fine,delicate,thread-like structures called root hairs,which absorb water and minerals from the soil.
