The tissue which participate in the secondary growth is

Options

A. a) Lateral meristem
B. b) Apical meristem
C. c) Intercalary meristem
D. d) Primary meristem

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks which tissue participates in secondary growth in plants. Secondary growth refers to the increase in thickness or girth of the plant, as opposed to primary growth, which increases the length.

2. **Identifying Types of Meristematic Tissues**: In plants, there are three main types of meristematic tissues:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for primary growth (length).
- **Intercalary Meristem**: Found at the base of leaves or internodes, also involved in primary growth.
- **Lateral Meristem**: Located along the sides of stems and roots, responsible for secondary growth (girth).

3. **Focusing on Lateral Meristem**: The lateral meristem is crucial for secondary growth. It includes:
- **Cork Cambium**: Produces cork cells that replace the epidermis.
- **Vascular Cambium**: Produces secondary xylem (wood) and secondary phloem (inner bark).

4. **Conclusion**: Since the question specifically asks for the tissue involved in secondary growth, the correct answer is **lateral meristem**.

5. **Final Answer**: Therefore, the tissue which participates in the secondary growth is **option A: lateral meristem**.
