Xylem vessels are found in:

Options

A. Gymnosperms only
B. Pteridophytes only
C. Angiosperms
D. Dicot plants only

Answer

**Step-by-Step Solution:**

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

2. **Identifying Xylem Vessels**: Xylem vessels, also known as tracheids, are specialized cells within the xylem that facilitate this transport. They are crucial for the plant's ability to move water efficiently.

3. **Occurrence in Plant Groups**: Xylem vessels are typically found in angiosperms, which are flowering plants. They are a characteristic feature of this group.

4. **Absence in Lower Plant Groups**: Xylem vessels are absent in lower plant groups such as bryophytes (mosses) and some types of gymnosperms. Instead, these plants have simpler structures for water transport.

5. **Conclusion**: Based on the information, xylem vessels are primarily found in angiosperms, making them a key feature of these flowering plants.

**Final Answer**: Xylem vessels are found in angiosperms.
