Pteridophytes have obvious differentiation of roots and leaves, and have been able to adapt to land. However, the roots, stems and leaves of bryophytes do not differentiate, but exist as flat leaflike bodies. Although mosses have differentiated roots and leaves, they are all false roots, and the stems and leaves are not lost to tissues, resulting in short plants! So bryophytes are obviously not as advanced as ferns! As for why gymnosperms are superior to ferns, there is no need to compare them. Obviously gymnosperms are higher than the whole spore plants, not to mention ferns, a branch of your spore plants. ! They are not comparable!
