The vascular cambium of dicot stem is

Options

A. Apical meristem
B. Intercallary meristem
C. Local meristem
D. Secondary meristem

Answer

To answer the question "The vascular cambium of dicot stem is," we need to analyze the options provided and understand the characteristics of vascular cambium.

### Step-by-Step Solution:

1. **Understanding Vascular Cambium**: Vascular cambium is a type of lateral meristem found in dicotyledonous plants (dicots). It is responsible for secondary growth, which increases the thickness (girth) of the plant stem and roots.

2. **Identifying Meristem Types**: There are different types of meristems:
- **Apical Meristem**: Responsible for primary growth (lengthening) of the plant.
- **Intercalary Meristem**: Responsible for growth at the base of leaves and internodes, also contributing to primary growth.
- **Lateral Meristem**: Includes vascular cambium and cork cambium, responsible for secondary growth.
- **Local Meristem**: This term can sometimes refer to lateral meristems.

3. **Focusing on the Question**: The question specifically asks about the vascular cambium in dicot stems. Since vascular cambium is a type of lateral meristem, we need to identify the correct option that describes it.

4. **Analyzing the Options**:
- **Option A (Apical meristem)**: Incorrect, as it is involved in primary growth.
- **Option B (Intercalary meristem)**: Incorrect, as it is also involved in primary growth.
- **Option C (Local meristem)**: This can refer to lateral meristems, including vascular cambium.
- **Option D (Secondary meristem)**: While vascular cambium is involved in secondary growth, this term is less commonly used to describe it directly.

5. **Conclusion**: The vascular cambium of dicot stems is best described as a **local meristem**, which is synonymous with lateral meristem.

### Final Answer:
The vascular cambium of dicot stem is **local meristem** (Option C).
