The main functions of the root is

Options

A. absorption of water and minerals
B. to provide proper anchorage of plant
C. to store reserve food material and synthesis of plant growth regulators
D. All of the above

Answer

### Step-by-Step Solution:

1. **Identify the Structure**: Understand that roots are part of vascular plants and are typically located underground.

2. **Main Functions of Roots**:
- **Anchorage**: Roots provide stability to the plant by anchoring it firmly in the soil.
- **Absorption**: Roots are responsible for absorbing water and essential minerals from the soil.
- **Conduction**: The absorbed water and minerals are then transported from the roots to the stem and other parts of the plant.
- **Storage**: Roots can store food materials for the plant's use.
- **Synthesis of Growth Regulators**: Roots are involved in the synthesis of plant hormones like auxins, which are important for growth and development.

3. **Conclusion**: Since roots perform multiple essential functions, including anchorage, absorption, conduction, storage, and synthesis of growth regulators, all the mentioned functions are correct.

4. **Correct Answer**: Therefore, the answer to the question about the main functions of the root is option D, which states that all the functions are correct.
