A primary meristem that produces secondary tissues is

Options

A. Apical meristem
B. Cork cambium
C. Inter fascicular cambium
D. Fascicular vascular cambium

Answer

To answer the question "A primary meristem that produces secondary tissues is," we need to analyze the options provided: apical meristem, cork cambium, interfascular cambium, and fascicular vascular cambium.

### Step-by-Step Solution:

1. **Understanding Primary Meristems**:
- Primary meristems are responsible for the primary growth of plants, which includes the elongation of roots and shoots. They are located at the tips of roots and shoots.

2. **Evaluating Apical Meristem**:
- The apical meristem is found at the growing tips of roots and shoots. It is responsible for primary growth but does not produce secondary tissues. Therefore, this option is incorrect.

3. **Evaluating Cork Cambium**:
- Cork cambium is a type of meristematic tissue that produces cork cells, which are part of the bark. However, cork cambium is considered a secondary meristem, not a primary one. Thus, this option is also incorrect.

4. **Evaluating Interfascular Cambium**:
- Interfascular cambium is located between the vascular bundles in dicot stems. While it is a primary meristem, it does not primarily produce secondary tissues. Therefore, this option is incorrect.

5. **Evaluating Fascicular Vascular Cambium**:
- Fascicular vascular cambium is found within the vascular bundles and is responsible for producing secondary xylem (wood) and secondary phloem (bark). It is a primary meristem that contributes to the formation of secondary tissues. Thus, this option is correct.

### Conclusion:
The correct answer is **fascicular vascular cambium**, as it is the primary meristem that produces secondary tissues.
