The four main regions of the roots are as follows:

1. Root cap: It is a thimble-like structure which protects the apex of the root from injuries as the root grows through the soil. It is also called the calyptra.

2. Region of meristematic activity: This region lies a few millimetres above the root cap. The cells of this region are thin-walled and have a dense protoplasm. They divide actively and add new cells.

3. Region of elongation: The cells of this region undergo elongation and enlargement. So, this region is responsible for the growth of the root. 

4. Region of maturation: This region is made up of the cells that have differentiated and matured. From this region, some of the epidermal cells form very fine and delicate thread-like structures called the root hairs. Because of this, this region is also called the piliferous region.
