The region or part of root that increases the sruface area for water absorption is

Options

A. Root cap
B. Zone of elongation
C. Meristematic zone
D. Root hair

Answer

To solve the question regarding which part of the root increases the surface area for water absorption, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Roots**: Roots have different regions, each with specific functions. The main regions include the root cap, zone of elongation, zone of maturation, and meristematic zone.

2. **Identify the Function of Each Region**:
- **Root Cap**: Protects the growing tip of the root as it pushes through the soil.
- **Zone of Elongation**: Where cells elongate, allowing the root to grow deeper into the soil.
- **Meristematic Zone**: Contains actively dividing cells that contribute to root growth.
- **Zone of Maturation**: This is where the root cells differentiate and mature.

3. **Focus on the Zone of Maturation**: In this zone, the cells develop specialized structures that enhance their function.

4. **Identify the Specialized Structures**: The epidermis of the root in the zone of maturation develops root hairs, which are unicellular extensions.

5. **Understand the Role of Root Hairs**: Root hairs significantly increase the surface area of the root, allowing for more efficient absorption of water and minerals from the soil.

6. **Conclude the Answer**: Therefore, the part of the root that increases the surface area for water absorption is the **root hairs** located in the **zone of maturation**.

### Final Answer:
The region or part of the root that increases the surface area for water absorption is **root hairs** in the **zone of maturation**.
