The elements of xylem tissue that store tannins are

Options

A. tracheids
B. vessels
C. xylem fibre
D. xylem parenchyma

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which element of xylem tissue is responsible for storing tannins.

2. **Identify the Components of Xylem**: The xylem tissue consists of several elements:
- Tracheids
- Vessels
- Xylem fibers
- Xylem parenchyma

3. **Analyze Each Element**:
- **Tracheids**: These are involved in the conduction of water and minerals, especially in pteridophytes and gymnosperms. They do not store tannins.
- **Vessels**: These also conduct water and minerals but are primarily found in angiosperms. They do not store tannins.
- **Xylem Fibers**: Their main function is to provide mechanical strength to the xylem. They do not store tannins.
- **Xylem Parenchyma**: This element is responsible for storing reserve food materials, including starch and other substances like tannins.

4. **Conclusion**: Based on the analysis, the element of xylem tissue that stores tannins is the **xylem parenchyma**.

5. **Final Answer**: The correct option is **xylem parenchyma**.
