Roots and its Functions

In plants life how roots and its functions are the important part of a plant.

The part of the plant that grows underground is called the root. Roots grow deep into the ground. They also spread wide, across the ground. Pull out some grass and compare its roots with the roots of the balsam plant. We can see that the roots are different. The bigger the tree, the deeper and more spread out are its roots. Different plants have different types of roots. Some plants have tap roots while others have fibrous roots.

Tap roots

A tap root has a main thick root. Tap root grows at the end of the stem which goes deep inside the soil. Out of the main root grow a number of thin roots.

Plants like neem, mango, carrot, mustard, bean and balsam have tap roots.

Fibrous roots

Fibrous roots have no main root. A number of roots that grow at the end of a stem are called fibrous roots. The roots of the plant go down deep in to the Earth and spread out. They hold the plant firmly in the soil. It helps the plants to stand up firmly even when a strong wind blows. 

Plants like rice, wheat and onion have fibrous roots.

Functions of the root

No plant can live or grow without roots. Hence, roots are very important.

(i) A root holds a plant erect and in one place.

(ii) Roots hold a plant firmly to the soil.

(iii) Roots absorb water and minerals from the soil and pass them to the plant.

(iv) Some roots store food for the plant.

Roots of plants like carrot, turnip, radish and beetroot store food. These can be eaten.

Now, we know how roots and its functions are the basic part of a plant.
