Which one of the following is considered first terrestrial plants to be evolved having xylem and phloem?

Options

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

Answer

To determine which of the following options is considered the first terrestrial plant to evolve with xylem and phloem, we can analyze each option provided:

1. **Bryophytes**: These are non-vascular plants, meaning they do not have xylem or phloem. They include mosses, liverworts, and hornworts. Therefore, they cannot be the answer.

2. **Gymnosperms**: These are seed-producing plants that include conifers. They evolved after pteridophytes and possess vascular tissues, but they are not the first terrestrial plants to have xylem and phloem.

3. **Pteridophytes**: This group includes ferns and horsetails. Pteridophytes are indeed the first terrestrial plants that evolved vascular tissues, including xylem and phloem. They are capable of transporting water, minerals, and nutrients, making them significant in the evolution of terrestrial flora.

4. **Angiosperms**: These are flowering plants that evolved after gymnosperms. They also possess vascular tissues, but they are not the first terrestrial plants.

Based on this analysis, the correct answer is **Pteridophytes**.

**Final Answer**: Pteridophytes are considered the first terrestrial plants to evolve with xylem and phloem.
