Wound healing in the matured part of the secondary stem occurs due to .

Options

A. Differentiation
B. De-differentiation
C. Re - differentiation
D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Wound Healing in Plants:**
Wound healing in plants is a crucial process that occurs when there is damage to the plant tissue. It involves the repair and regeneration of the damaged area.

2. **Role of Secondary Meristem:**
The healing process primarily involves the activity of secondary meristems. Secondary meristems are tissues that arise from permanent tissues and are responsible for secondary growth in plants.

3. **De-differentiation Process:**
De-differentiation is the process where mature cells lose their specialized functions and regain the ability to divide. This is essential for wound healing as it allows the formation of new cells to replace the damaged ones.

4. **Differentiation vs. Re-differentiation:**
- **Differentiation** refers to the process where cells mature and take on specialized functions. This is not involved in wound healing.
- **Re-differentiation** occurs when de-differentiated cells mature again after they have divided. This is also not the primary process involved in initial wound healing.

5. **Conclusion:**
Given the definitions and processes, the correct answer to the question "Wound healing in the matured part of the secondary stem occurs due to" is **de-differentiation**.

**Final Answer:**
Wound healing in the matured part of the secondary stem occurs due to **de-differentiation**.
