Function of xylem ray parenchyma is

Options

A. Upward conduction
B. Radial conduction
C. Downward conduction
D. 1 and 3

Answer

### Step-by-Step Solution:

1. **Understanding Xylem Ray Parenchyma**:
- Xylem ray parenchyma is a type of parenchyma tissue found in the xylem of vascular plants. It consists of living cells that are involved in various functions.

2. **Storage Function**:
- One of the primary functions of xylem ray parenchyma is to serve as a storage space for the plant. These cells store essential substances such as starch, fats, and tannins.

3. **Radial Conduction**:
- Xylem ray parenchyma is also involved in the conduction of water. This conduction occurs radially, meaning that water can move laterally across the plant through these cells.

4. **Connection to Other Xylem Components**:
- The xylem ray parenchyma cells are closely associated with other xylem elements, such as vessels and tracheids. They help facilitate the movement of water and nutrients by connecting to these structures.

5. **Conclusion**:
- In summary, the xylem ray parenchyma primarily functions in the storage of substances and assists in the radial conduction of water within the plant.
