Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.
Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.
