Consider the following functions for plants :

A. To give support to the plant

B. To provide humus

C. To store food

D. To absorb water and minerals

The functions of roots are

The correct option is A, C and D.

Let us analyze each of the given functions to determine the role of plant roots:

Statement A: To give support to the plant
Roots anchor the plant firmly into the soil, providing structural stability and support so that the plant remains upright.

Statement B: To provide humus
Humus is formed in the soil through the decomposition of dead organic matter by microorganisms. Roots do not provide humus to the plant, so this statement is incorrect.

Statement C: To store food
In many plants (such as carrots, radishes, and sweet potatoes), roots act as storage organs that store food produced by the plant.

Statement D: To absorb water and minerals
The primary function of roots is to absorb essential nutrients, minerals, and water from the soil and transport them to the rest of the plant.

Therefore, statements A, C, and D accurately describe the functions of roots, making A, C and D the correct choice.
