The diploid sporphyte is represented by a dominant, independent, photoshynthetic, vascular plant body. It alternates with multicellular, saprophytic/autotrophic, independent but short-lived haploid gametophyte. This type of pattern is exhibited by

1. Bryophytes (Sphagnum, Polytrichum).

2.Pteridophytes (Selaginella, Lycopodium).

3. Most of the algal genera (Fucus, Chara, Polysiphonia).

4. Seed plants (gymnosperms and antiosperms).
