Explanation

Pteridophytes are vascular plants that include ferns and horsetails. Unlike bryophytes (mosses), they possess well-developed xylem and phloem tissues for efficient water and nutrient transport. Flowering plants are angiosperms, which evolved later. Pteridophytes have multicellular sex organs, not unicellular ones.
