The pteridophytes exhibit, alternation of dominant sporophytic generation with an inconspicuous gametophytic generation. The sporophyte is differentiated into root, stem and leaves while the small and inconspicuous gametophyte is independent and autotrophic. The most conspicuous phase in the life-cycle of bryophytes is the gametophyte. It is independent and concerned with sexual reproduction. The sporophyte is simpler than gametophyte and originally attached to parent gametophyte throughout its life. It is dependent upon it partially or wholly for its nutrition. The plant body of gymnospermic plant is sporophytic and differentiated into roots, stems and leaves. The male and female gametophytes are distinct,
