Region of root from base tip in a tap root are

Options

A. Maturation zone (MZ)-Cell division zone (CDZ)-Elongation zone (EZ)
B. MZ-EZ-CDZ
C. CDZ-EZ-MZ
D. EZ-CDZ-MZ

Answer

To answer the question regarding the regions of a taproot from the base to the tip, we can break down the structure of the root into three main regions. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the Root Structure**: Understand that a taproot consists of several distinct regions that perform different functions.

2. **Root Cap**: At the very tip of the root is the root cap, which protects the growing tip as it pushes through the soil.

3. **Meristematic Region**: Just above the root cap is the meristematic region, also known as the cell division zone. This area contains actively dividing cells that contribute to root growth.

4. **Elongation Zone**: Following the meristematic region is the elongation zone. In this area, the cells that were produced in the meristematic region begin to elongate, which helps in increasing the length of the root.

5. **Maturation Zone**: Above the elongation zone is the maturation zone. In this region, the cells mature and differentiate into various types of cells. This is also where root hairs develop, which are essential for water and nutrient absorption.

6. **Order of Regions**: Therefore, from the base to the tip, the order of the regions in a taproot is:
- **Cell Division Zone (Meristematic Region)**
- **Elongation Zone**
- **Maturation Zone**

### Final Answer:
The regions of the root from the base to the tip in a taproot are:
- Cell Division Zone (Meristematic Region)
- Elongation Zone
- Maturation Zone
