The first terrestrial plants to possess vascular tissues are `:`

Options

A. Bryophytes
B. Pteridophytes
C. Gymnosperms
D. Angiosperms

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Groups**:
- The plant kingdom is divided into various groups based on certain characteristics. The main groups include Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.

2. **Defining Bryophytes**:
- Bryophytes, which include mosses and liverworts, are non-vascular plants. They do not have true roots, stems, or leaves, and they depend on water for sexual reproduction. They are often referred to as the amphibians of the plant kingdom.

3. **Identifying Pteridophytes**:
- Pteridophytes, such as ferns and horsetails, are the first group of terrestrial plants that possess vascular tissues. These vascular tissues include xylem and phloem, which are essential for the transport of water, nutrients, and food throughout the plant.

4. **Differentiating Gymnosperms and Angiosperms**:
- Gymnosperms (like conifers) and Angiosperms (flowering plants) evolved after Pteridophytes. While they also possess vascular tissues, they are not the first terrestrial plants to have them.

5. **Conclusion**:
- Based on the characteristics and evolutionary timeline, the first terrestrial plants to possess vascular tissues are Pteridophytes.

**Final Answer**: The first terrestrial plants to possess vascular tissues are **Pteridophytes**.
