Wound healing is due to

Options

A. Primary meristem
B. Secondary meristem
C. Ventral meristem
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Wound Healing in Plants**: Wound healing in plants is a process that occurs when a plant is damaged. It involves the regeneration of tissues to repair the injury.

2. **Identifying Types of Meristems**: There are different types of meristems in plants:
- **Apical Meristems**: These are also known as primary meristems and are located at the tips of roots and shoots. They are responsible for the elongation of the plant.
- **Secondary Meristems**: These are involved in the thickening of the plant and are found in the lateral regions.
- **Ventral Meristems**: This term is not commonly used in the context of plant meristems and may refer to specific regions in certain plants.

3. **Role of Meristems in Wound Healing**: Meristems are responsible for the formation of new cells. When a plant is wounded, the meristematic tissues can produce new cells to replace the damaged ones.

4. **Conclusion on the Correct Option**: Since apical meristems (primary meristems) are responsible for generating new cells in the injured tissues, the correct answer to the question of what wound healing is due to is **primary meristem**.

5. **Final Answer**: The correct option is **primary meristem** (Option 1).
