Interfascicular cambium are formed due to

Options

A. cell division
B. cell differentiation
C. cell dedifferentiation
D. redifferentiation

Explanation

**Step-by-Step Solution:**

1. **Understanding Interfascicular Cambium**: Interfascicular cambium is a type of cambium that forms between vascular bundles in dicotyledonous plants. It plays a crucial role in secondary growth, contributing to the formation of secondary xylem and phloem.

2. **Defining Key Terms**:
- **Cell Division**: This is the process where a parent cell divides to produce two or more daughter cells.
- **Cell Differentiation**: This is the process where unspecialized cells mature into specialized cells with specific functions.
- **Cell De-differentiation**: This occurs when differentiated cells regain the ability to divide and revert to a more meristematic state.
- **Re-differentiation**: This is when de-differentiated cells lose their ability to divide again and mature into specialized cells.

3. **Analyzing the Options**:
- **Cell Division**: While this is a fundamental process, it does not specifically explain the formation of interfascicular cambium.
- **Cell Differentiation**: This process leads to the maturation of cells, which is not directly responsible for the formation of interfascicular cambium.
- **Cell De-differentiation**: This process allows previously differentiated cells to regain the ability to divide, which is relevant to cambium formation.
- **Re-differentiation**: This involves the maturation of cells after they have de-differentiated, which is also not the primary process for forming interfascicular cambium.

4. **Conclusion**: The correct answer is that interfascicular cambium is formed due to **cell de-differentiation**. This process allows differentiated cells to regain their capacity to divide and contribute to the formation of the cambial layer.
