included cork is cork generally formed in

Options

A. cortex
B. pericycle or interfascicular parenchyma
C. Xylem
D. pith

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where included cork is generally formed among the given options: cortex, pericycle, intrafasicular parenchyma, xylem, or pith.

2. **Definition of Included Cork**: Included cork refers to the cork that develops within the plant structure, specifically between the layers of secondary xylem.

3. **Formation of Included Cork**: The included cork is formed as a result of the activity of the cork cambium (phellogen). This cambium produces cork cells that are located between the layers of secondary xylem.

4. **Analyzing the Options**:
- **Cortex**: This is the outer layer of the stem and does not contribute to included cork.
- **Pericycle**: This is a layer of cells just inside the endodermis in roots and does not form included cork.
- **Intrafasicular Parenchyma**: This is part of the vascular bundle and does not contribute to included cork.
- **Xylem**: This is where included cork is formed, specifically between the layers of secondary xylem.
- **Pith**: This is the central part of the stem and does not form included cork.

5. **Conclusion**: Based on the analysis, the correct answer is that included cork is generally formed in the xylem.

**Final Answer**: Included cork is generally formed in the xylem.
