The maximum absorption of water by roots occurs in the (region) zone of

Options

A. Root cap
B. Cell division
C. Cell elongation
D. Cell maturation

Answer

To solve the question regarding the maximum absorption of water by roots, we will analyze the different zones of the root and their functions:

### Step-by-Step Solution:

1. **Understanding Root Zones**: Roots have different zones, each with specific functions. The main zones are:
- Root Cap
- Zone of Cell Division
- Zone of Cell Elongation
- Zone of Cell Maturation

2. **Function of Each Zone**:
- **Root Cap**: This is the protective tip of the root that helps it penetrate the soil. It does not play a significant role in water absorption.
- **Zone of Cell Division**: This zone is responsible for the growth of new cells. While it is crucial for root growth, it does not have root hairs, which are essential for water absorption.
- **Zone of Cell Elongation**: In this zone, cells grow longer, contributing to root length. However, like the previous zone, it lacks root hairs.
- **Zone of Cell Maturation**: This zone is where cells differentiate and mature. It is in this zone that root hairs, which are extensions of the root epidermis, are present.

3. **Role of Root Hairs**: Root hairs are tiny, hair-like structures that increase the surface area of the root, allowing for maximum absorption of water and nutrients from the soil.

4. **Conclusion**: Since root hairs are primarily found in the zone of cell maturation, this is where the maximum absorption of water occurs.

Thus, the answer to the question is that the maximum absorption of water by roots occurs in the **zone of cell maturation**.

### Final Answer:
The maximum absorption of water by roots occurs in the **zone of cell maturation**.
