Y-shaped arrangment of xylem vessel is found in

Options

A. monocot stem
B. dicot stem
C. monocot root
D. dicot root.

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of Plants**:
- Plants can be categorized into two main groups based on their cotyledons: monocots (one cotyledon) and dicots (two cotyledons). This classification helps in understanding the structure and arrangement of various plant tissues.

2. **Identifying Xylem Vessels**:
- Xylem vessels are responsible for the transport of water and minerals from the roots to other parts of the plant. Their arrangement can vary between monocots and dicots.

3. **Analyzing Monocot Stem Structure**:
- In monocot stems, the vascular bundles (which include xylem) are scattered throughout the stem. This arrangement is different from that of dicot stems, where vascular bundles are arranged in a ring.

4. **Recognizing the Y-shaped Arrangement**:
- The xylem vessels in monocots often exhibit a Y-shaped arrangement. This is due to the specific way in which the protoxylem (the first formed xylem) is oriented towards the center of the stem, creating a Y shape.

5. **Conclusion**:
- Based on the above points, the Y-shaped arrangement of xylem vessels is specifically found in the monocot stem.

**Final Answer**: The Y-shaped arrangement of xylem vessels is found in the monocot stem.
