Vessels are found in

Options

A. all angiosperms and some gymnosperms
B. most of angiosperms and few gymnosperms
C. all angiosperms and few gymnosperms and some pterdophytes
D. all pteridophytes

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Vessels**: Vessels are specialized structures in plants that are responsible for the conduction of water and minerals. They are long cylindrical tubes made up of vessel elements or members.

2. **Identifying Plant Groups**: Vessels are primarily found in angiosperms, which are flowering plants. They are considered the most advanced group of plants.

3. **Gymnosperms and Vessels**: While most gymnosperms do not have vessels, there are exceptions. For example, some gymnosperms like Gnetophytes (which include the genus Ephedra) do possess vessels.

4. **Evaluating the Options**:
- **Option 1**: All angiosperms and some gymnosperms - This is a strong candidate since all angiosperms have vessels, and some gymnosperms do as well.
- **Option 2**: Most of angiosperms and some gymnosperms - This is incorrect because all angiosperms have vessels, not just most.
- **Option 3**: All angiosperms and few gymnosperms and some pteridophytes - This is incorrect as pteridophytes do not have vessels.
- **Option 4**: All pteridophytes - This is incorrect because pteridophytes do not contain vessels.

5. **Conclusion**: The correct answer is **Option 1: All angiosperms and some gymnosperms**.
