Which of the following is formed after dedifferentiation?

Options

A. Secondary phloem
B. Secondary cortex
C. Paranchyma
D. Interfascicular vascular cambium

Answer

**Step-by-Step Solution:**

1. **Understanding Differentiation**: Differentiation is the process by which meristematic tissue, which is capable of rapid division, develops into permanent tissue. This permanent tissue has a specific shape, size, and function and loses the ability to divide.

2. **Understanding Dedifferentiation**: Dedifferentiation is the process where differentiated cells, which have lost their ability to divide, regain this capacity. This means that cells that were once specialized can revert to a more primitive state where they can divide again.

3. **Understanding Re-differentiation**: After dedifferentiation, when these cells start dividing again and then specialize into mature cells, this process is known as re-differentiation.

4. **Identifying the Correct Answer**: The question asks which structure is formed after dedifferentiation. Among the options provided:
- Secondary phloem
- Cortex
- Parenchyma
- Interfascicular vascular cambium

The interfascicular vascular cambium is formed after dedifferentiation. This tissue is responsible for lateral growth and contributes to the increase in the girth of the plant.

5. **Conclusion**: Therefore, the correct answer is the **interfascicular vascular cambium**.
