The peculiar character of pteridophyte is
1 Presence of roots, leaves
2 Dominant sporophyte with an autotrophic gametophyte
3 Dominant sporophyte
4 Gametophyte reduced
Explanation:
In pteridophytes, sporophyte and gametophyte are both multicellular, independent, photosynthetic structures. Although, sporophyte in the main plant body and bears true roots, stem and leaves.

From evolutionary point of view, retention of the female gametophyte with developingyoung embryo on the parent sporophyte for some time, is first observed in
1 Liverworts
2 Mosses
3 Pteridophytes
4 Gymnosperms
Explanation:
In Pteridophyte, megaspore is retained for some times in female gametophyte, however the permanent retention is required for seed formation in Gymnosperms. That’s why Pteridophytes exhibit precursor to seed habit only.
