Answer

To identify the correct order of the root zones, we need to understand the functions and sequence of the different regions in a root. Here’s the step-by-step breakdown:

1. **Meristematic Zone**: This is the region at the tip of the root where active cell division occurs. The cells here are small, with dense cytoplasm and thin cell walls, allowing them to divide rapidly. This zone is crucial for the growth of the root.

**Hint**: Remember that the meristematic zone is where new cells are generated, making it the starting point of root growth.

2. **Water Absorption Zone**: Following the meristematic zone, this zone is responsible for absorbing water. The root hairs, which are extensions of the root epidermis, are present in this zone and increase the surface area for water absorption.

**Hint**: Think of this zone as the area where the root starts to take in essential resources from the soil.

3. **Mineral Absorption Zone**: After the water absorption zone, this zone is primarily involved in the uptake of minerals from the soil. The root hairs also play a role here, as they help in the absorption of essential nutrients.

**Hint**: This zone focuses on gathering minerals, which are crucial for the plant's growth and development.

4. **Maturation Zone**: This is the final zone located near the base of the stem. In this region, the cells have differentiated and matured. Although it does not actively participate in absorption, it provides support to the root.

**Hint**: Consider this zone as the area where the root stabilizes and supports the plant structure.

Now, putting these zones in order based on their functions and positions from the tip of the root to the base, we get:

- **1. Meristematic Zone (2)**
- **2. Water Absorption Zone (4)**
- **3. Mineral Absorption Zone (1)**
- **4. Maturation Zone (3)**

Thus, the correct order is **2, 4, 1, 3**.

### Final Answer:
The correct order is **2, 4, 1, 3**.
