Vascular cambium of the root is an example of

Options

A. Apical meristem
B. Intercalary meristem
C. Secondary meristem
D. Root apical meristem

Answer

To determine the type of meristem that the vascular cambium of the root represents, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Vascular Cambium**: The vascular cambium is a type of meristematic tissue that is responsible for the production of secondary xylem (wood) and secondary phloem (bark) in plants. It is located between the xylem and phloem in the vascular bundles.

2. **Identify the Options**: The question provides four options:
- Option 1: Apical meristem
- Option 2: Intercalary meristem
- Option 3: Secondary meristem
- Option 4: Root apical meristem

3. **Evaluate Each Option**:
- **Option 1: Apical Meristem**: This type of meristem is found at the tips of roots and shoots and is responsible for primary growth (elongation). Since vascular cambium is involved in secondary growth, this option is incorrect.
- **Option 2: Intercalary Meristem**: This meristem is found at the nodes and is responsible for regrowth after damage. It does not relate to the vascular cambium, so this option is also incorrect.
- **Option 3: Secondary Meristem**: The vascular cambium is indeed classified as a secondary meristem because it contributes to secondary growth by producing secondary xylem and phloem. This option is correct.
- **Option 4: Root Apical Meristem**: Similar to the apical meristem, this is found at the root tip and is responsible for root elongation. Therefore, this option is also incorrect.

4. **Conclusion**: After evaluating all the options, the correct answer is **Option 3: Secondary Meristem**, as the vascular cambium is a type of secondary meristem that facilitates secondary growth in roots and shoots.

### Final Answer:
The vascular cambium of the root is an example of **Secondary Meristem**.
