Root hairs are present in

Options

A. Zone of elongation
B. Zone of meristematic activity
C. Root cap
D. Zone of maturation

Answer

To determine where root hairs are present, we will analyze the different zones of the root and identify the correct one.

### Step-by-Step Solution:

1. **Understanding Root Zones**: The root is divided into several zones, each with specific functions. The main zones are:
- Zone of Meristematic Activity
- Zone of Elongation
- Zone of Maturation
- Root Cap

2. **Evaluating the Zone of Elongation**:
- This zone is where the cells increase in size and number, contributing to the growth of the root.
- Root hairs are not present in this zone because it primarily focuses on cell elongation rather than differentiation.

**Hint**: Remember that root hairs are specialized structures for absorption, not growth.

3. **Evaluating the Zone of Meristematic Activity**:
- This zone contains actively dividing cells (meristematic tissue).
- Since root hairs are extensions of differentiated cells, they do not form in this zone as the cells are still in the process of dividing.

**Hint**: Think about where cells are actively dividing versus where they are specialized for function.

4. **Evaluating the Root Cap**:
- The root cap is a protective structure at the tip of the root that helps the root push through the soil.
- Root hairs are not found here as this area is primarily protective and does not serve the function of absorption.

**Hint**: Consider the role of the root cap in protecting the root rather than in absorption.

5. **Evaluating the Zone of Maturation**:
- This zone is where cells differentiate and mature into specific types, including root hairs.
- Root hairs are indeed present in this zone, as it is where the cells have completed their elongation and are specialized for absorption.

**Hint**: Focus on the function of root hairs and where cells become specialized for that function.

### Conclusion:
Root hairs are present in the **Zone of Maturation**. Therefore, the correct answer is option 4.
