Which xylem element store food material in the form of starch or fats and other substances like tannin?

Answer

**Step-by-Step Solution:**

1. **Understanding Xylem**: Xylem is a type of vascular tissue in plants responsible for the transport of water and minerals from the roots to the rest of the plant. It also provides structural support.

2. **Types of Xylem Elements**: Xylem is composed of several types of elements, which include:
- Tracheids
- Vessels
- Xylem Fibers
- Xylem Parenchyma

3. **Functions of Xylem Elements**:
- **Tracheids**: These are elongated cells that help in the transport of water and minerals.
- **Vessels**: These are wider cells that also assist in water transport and provide mechanical strength.
- **Xylem Fibers**: These provide additional strength and support to the plant while also aiding in water transport.
- **Xylem Parenchyma**: This is the only living component of xylem and is primarily involved in storage.

4. **Storage Function of Xylem Parenchyma**: Among all the xylem elements, xylem parenchyma is responsible for storing food materials such as starch, fats, oils, and other substances like tannins.

5. **Conclusion**: Therefore, the xylem element that stores food material in the form of starch or fats and other substances like tannin is **xylem parenchyma**.

**Final Answer**: Xylem Parenchyma
