Which of the following meristem classification is based on position in the plant body ?

Options

A. Primary meristem
B. intercalary meristem
C. secondary meristem
D. Procambial meristem

Answer

To determine which classification of meristem is based on the position in the plant body, we will analyze each option systematically.

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions in plants where cells are actively dividing, leading to growth. They can be classified based on various criteria, including their position in the plant body.

2. **Evaluating the Options**:
- **Option 1: Primary Meristem**:
- Primary meristems are involved in the primary growth of the plant, which occurs during the early stages of development. They include the protoderm, ground meristem, and procambium. This classification is based on the type of growth rather than position.

- **Option 2: Intercalary Meristem**:
- Intercalary meristems are located at the nodes of the plant, between the internodes. This means they are specifically positioned within the plant structure, making this classification based on position.

- **Option 3: Secondary Meristem**:
- Secondary meristems are responsible for secondary growth, which increases the girth of the plant. Similar to primary meristems, this classification is based on growth type and not position.

- **Option 4: Procambium**:
- The procambium is a type of primary meristem that develops into vascular tissues. While it is crucial for early plant development, it does not pertain to the position in the plant body.

3. **Conclusion**:
- After evaluating all the options, the **Intercalary Meristem** (Option 2) is the correct answer as it is classified based on its position in the plant body, specifically located at the nodes.

### Final Answer:
- The correct classification of meristem based on position in the plant body is **Intercalary Meristem** (Option 2).
