Vessels are major water conducting cells in

Options

A. Xylem of angiosperms
B. Xylem of gymnosperms
C. Both 1 and 2
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where vessels, which are major water-conducting cells, are found.

2. **Identifying Vessels**: Vessels are specialized structures in plants that facilitate the transport of water. They are primarily found in the xylem tissue.

3. **Xylem in Angiosperms**: In angiosperms (flowering plants), vessels are a key component of the xylem. They are long, cylindrical structures formed from vessel members that allow efficient water conduction.

4. **Xylem in Gymnosperms**: In gymnosperms (non-flowering plants), vessels are generally absent. However, there are exceptions, such as in certain groups like the Gnetophytes, where vessels can be found.

5. **Evaluating the Options**:
- **Option 1**: Xylem of angiosperms - Correct, as vessels are present.
- **Option 2**: Xylem of gymnosperms - Generally incorrect, as vessels are absent in most gymnosperms.
- **Option 3**: Both one and two - Incorrect, since not all gymnosperms have vessels.
- **Option 4**: None of these - Incorrect, since vessels are present in angiosperms.

6. **Conclusion**: The correct answer is that vessels are major water-conducting cells in the xylem of angiosperms.

**Final Answer**: Vessels are major water conducting cells in the xylem of angiosperms.
