Interfascicular cambium is

Options

A. Primary meristem
B. Secondary meristem
C. Abnormal meristem
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Interfascicular Cambium**:
- Interfascicular cambium is a type of cambium located between vascular bundles in a plant. It plays a crucial role in the growth and development of the plant.

2. **Classification of Meristems**:
- Meristems are classified into three main types: primary meristems, secondary meristems, and abnormal meristems.
- Primary meristems are responsible for the initial growth of the plant, while secondary meristems contribute to the increase in thickness or girth of the plant.

3. **Identifying the Type of Cambium**:
- Interfascicular cambium is formed from non-meristematic (permanent) tissue during the later stages of a plant's life.
- It is involved in secondary growth, which means it is responsible for the formation of secondary tissues.

4. **Conclusion**:
- Since interfascicular cambium develops from permanent tissue and contributes to secondary growth, it is classified as a secondary meristem.

5. **Final Answer**:
- Therefore, the correct answer to the question "Interfascicular cambium is" is **secondary meristem**.
