Question

Explain various kinds of roots with the help of an example.

Answer 1

There are two main types of root systems: tap root and fibrous root system.

(i) Tap root system- Tap root has only one main and long root. The smaller roots that grow from the main root are called lateral roots. They are also called true roots. Tap root grows vertically deep into the soil and has extremely large surface area. A single plant has only one tap root. Tap roots are found in plants which have reticulate venation in their leaves.

Examples: Mango, neem, pea, carrot, beetroot, pine, etc.

(ii) Fibrous root system- Fibrous roots do not have a main root. They grow from the base of the stem and have a bushy appearance. Fibrous roots are short and most of them grow horizontally in the soil. They are found in plants which have parallel venation in their leaves. A single plant can have hundreds of fibrous roots.

Examples: Grass, maize, wheat, onion, sugarcane, rice, etc.
