Intercalary meristem is derived from

Options

A. Iateral meristem
B. apical meristem
C. interfascicular cambium
D. protoderm

Answer

**Step-by-Step Solution:**

1. **Understanding Meristems**: Begin by recognizing that meristems are tissues in plants that are capable of continuous cell division. They are primarily classified into two types: primary meristems and secondary meristems.

2. **Identifying Primary Meristems**: Primary meristems are responsible for the primary growth of plants, which includes elongation of roots and shoots. The key types of primary meristems are apical meristems and intercalary meristems.

3. **Defining Intercalary Meristem**: The intercalary meristem is a type of primary meristem that is found at the nodes of the stem. It plays a crucial role in the growth of the plant by allowing for elongation at specific regions.

4. **Source of Intercalary Meristem**: The intercalary meristem is derived from the cells of the apical meristem. As the plant grows, the apical meristem at the tip of the shoot produces new cells. Some of these cells remain at the nodes and differentiate into intercalary meristem.

5. **Eliminating Other Options**:
- Lateral meristem is involved in secondary growth and does not give rise to intercalary meristem.
- Interfascicular meristem is also a type of lateral meristem and is not related to the formation of intercalary meristem.
- Protoderm primarily gives rise to the epidermis and does not contribute to intercalary meristem.

6. **Conclusion**: Based on the above analysis, the intercalary meristem is derived from the apical meristem, making it the correct answer.

**Final Answer**: Intercalary meristem is derived from the apical meristem.
