Cells of the cambium present between primary xylem and primary phloem is

Options

A. Intrafascicular cambium
B. Interfascicular cambium
C. Wound cambium
D. Cork cambium

Answer

To solve the question regarding the cells of the cambium present between primary xylem and primary phloem, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Xylem and Primary Phloem**:
- Primary xylem is the type of xylem that is formed during the primary growth of plants, originating from the procambium in the root and shoot apex.
- Primary phloem is similarly formed from the procambium during primary growth.

2. **Identifying the Cambium**:
- The cambium is a layer of meristematic tissue that is responsible for secondary growth in plants. It is crucial for the formation of new vascular tissues.

3. **Locating the Cambium Between Xylem and Phloem**:
- The cambium that is located specifically between the primary xylem and primary phloem is referred to as the **fascicular cambium**. This cambium is responsible for the production of secondary xylem and phloem.

4. **Conclusion**:
- The correct term for the cambium present between primary xylem and primary phloem is **intrafascicular cambium** or **fascicular cambium**.

5. **Evaluating Other Options**:
- **Interfascicular cambium**: This is found between two vascular bundles and is not the correct answer.
- **Wound cambium**: This forms in response to injury and is not relevant to the primary xylem and phloem.
- **Cork cambium**: This is part of the epidermis and is also not the correct answer.

### Final Answer:
The cells of the cambium present between primary xylem and primary phloem is called **intrafascicular cambium**.
