Interfascicular cambium develops from the cell of

Options

A. xylem parenchyma
B. endodermis
C. pericycle
D. medullary rays

Answer

**Step-by-Step Solution:**

1. **Understanding Interfascicular Cambium**: Interfascicular cambium is a type of cambium that develops between vascular bundles in dicot stems. It is responsible for secondary growth, which increases the thickness of the plant.

2. **Identifying Possible Sources**: The options provided for the development of interfascicular cambium include:
- Xylem parenchyma
- Endodermis
- Pericycle
- Medullary rays

3. **Analyzing Each Option**:
- **Xylem Parenchyma**: This tissue is involved in water transport and storage but does not contribute to the formation of interfascicular cambium.
- **Endodermis**: This is the innermost layer of the cortex and has a protective function. It does not develop into interfascicular cambium.
- **Pericycle**: This layer surrounds the vascular bundles and provides protection but does not form interfascicular cambium.
- **Medullary Rays**: These are the correct source as they connect the vascular bundles and are responsible for the formation of interfascicular cambium.

4. **Conclusion**: The interfascicular cambium develops from the cells of medullary rays.

**Final Answer**: Interfascicular cambium develops from the cells of **medullary rays**.
