Vessels are present in which one of the following groups of plants ?

Options

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

Answer

To determine which group of plants contains vessels, we can analyze the four options provided: Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.

### Step-by-Step Solution:

1. **Understand the Groups of Plants**:
- **Bryophytes**: This group includes mosses and liverworts. They are considered lower plants and have a simple structure. Their body is thalloid and not well differentiated into roots, stems, and leaves. They do not have vascular tissues, which means they lack vessels.

2. **Examine Pteridophytes**:
- **Pteridophytes**: This group includes ferns and horsetails. They are the first terrestrial plants to develop vascular tissues, which include xylem and phloem. However, they primarily have tracheids in their xylem and do not possess vessels.

3. **Look at Gymnosperms**:
- **Gymnosperms**: This group includes plants with naked seeds, such as conifers. While they do have vascular tissues, their xylem typically contains only tracheids and lacks vessels. Therefore, vessels are not present in gymnosperms.

4. **Identify Angiosperms**:
- **Angiosperms**: This group consists of flowering plants. They are characterized by the presence of vessels in their xylem, which are crucial for efficient water transport. Angiosperms are the only group among the options that have vessels.

### Conclusion:
Based on the analysis, vessels are present in **Angiosperms**.
