C.Root cap zone , D.Zone of maturation
E.Zone of elongation

Options

A. C, B, E, A, D
B. A, B, C, D, E
C. D, E, A, C, B
D. E, D, C, B,A

Answer

To rearrange the zones of the root as seen in a vertical section, we need to understand the order in which these zones appear from the tip of the root to the base. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Zones**: We have the following zones to arrange:
- A. Root hair zone
- B. Zone of meristems
- C. Root cap zone
- D. Zone of maturation
- E. Zone of elongation

2. **Understand the Structure of the Root**: In a vertical section of the root, the zones are arranged in a specific order from the tip of the root downwards.

3. **Order of the Zones**:
- **Root Cap Zone (C)**: This is the first zone at the very tip of the root. It protects the root as it pushes through the soil.
- **Zone of Meristems (B)**: Just behind the root cap, this zone contains actively dividing cells that contribute to root growth.
- **Zone of Elongation (E)**: Following the meristematic zone, this area is where the cells elongate, allowing the root to grow longer.
- **Root Hair Zone (A)**: After elongation, the root hair zone is where root hairs develop to increase surface area for water and nutrient absorption.
- **Zone of Maturation (D)**: This is the final zone where cells differentiate and mature into various types of root cells.

4. **Final Arrangement**: Based on the above understanding, the correct order from the tip of the root to the base is:
- C (Root cap zone)
- B (Zone of meristems)
- E (Zone of elongation)
- A (Root hair zone)
- D (Zone of maturation)

5. **Select the Correct Option**: The correct sequence is C, B, E, A, D, which corresponds to option A.

### Final Answer:
The correct order of the zones in the root from the tip to the base is: **C, B, E, A, D** (Option A).
