Single tubular root cells make up root hair cells (black arrow pointing to one of the root hair cells). Their unique lateral elongation boosts the root system's contact surface with the soil. Root hairs form the rhizosphere and mostly take up water and nutrients.

The basic structure of roots:

Only the ends of roots develop in length. A thimble-shaped root cap protects the growing tip of the root as it travels through the earth at its very tip. The apical meristem, a region containing actively dividing cells, is located immediately behind the root cap.

The function of roots:

They provide three main functions: they absorb water and minerals, they anchor and support the plant, and they store food. Water and mineral absorption To effectively absorb water and dissolved minerals from the soil, root hairs and thin-walled epidermal cells are ideally adapted.

The structure of root hair is explained below:

Explanation:

1. The size of a root hair may range from 1 to 10 mm in length and is tube like in appearance.

2. Root hair generally is an elongation which arises from the cells of epiblema.

3. There are two layers found in root hair. The outer layer has pectin and the inner layer has cellulose in it.

4. Root hair also has cell wall around its cells which prevents it from any mechanical damaged and protects from stress and unfavourable conditions.

5. Apart from all these, root hairs also has a large vacuole in the centre which is surrounded by cytoplasm and plasma membrane.

6. The cell wall which surrounds the root hair is permeable, that is, it allows the movement of substances or materials in and out of root hair cells.

7. We can find root hairs in the absorption zone of the roots.

8. The main function or role of root hairs is to absorb water from the soil so that plants can use it for their metabolic activity.
