Vessels are present in which one of the following groups of plants ?
1 Bryophyta
2 Pteridophyta
3 Gymnosperms
4 Angiosperms

Options

A. Bryophyta
B. Pteridophyta
C. Gymnosperms
D. Angiosperms

Answer

To determine which group of plants contains vessels, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Vessels in Plants**:
- Vessels are part of the xylem, which is responsible for the transportation of water and minerals in plants.

2. **Analyzing Bryophyta**:
- Bryophytes are non-vascular plants. They do not possess a vascular system, which means they lack both xylem and phloem.
- **Conclusion**: Vessels are not present in Bryophyta.

3. **Analyzing Pteridophyta**:
- Pteridophytes are vascular plants but are considered seedless. They have a vascular system, but it is not fully developed.
- They contain tracheids but do not have vessels in their xylem.
- **Conclusion**: Vessels are not present in Pteridophyta.

4. **Analyzing Gymnosperms**:
- Gymnosperms are seed-bearing plants with a vascular system. However, their xylem lacks vessels; instead, they primarily have tracheids.
- **Conclusion**: Vessels are not present in Gymnosperms.

5. **Analyzing Angiosperms**:
- Angiosperms are flowering plants that have a fully developed vascular system. They possess both vessels and companion cells in their xylem and phloem, respectively.
- **Conclusion**: Vessels are present in Angiosperms.

### Final Answer:
The group of plants that contains vessels is **4. Angiosperms**.
