Key differences, features, and comparative analysis of Type and Dominant phase.
| Type | Dominant phase | Other phase | Found in |
|---|---|---|---|
| Haplontic | Gametophyte (n), free-living | Only the zygote is diploid; zygote undergoes meiosis | Many algae — Volvox, Spirogyra, Chlamydomonas |
| Diplontic | Sporophyte (2n), free-living | Gametophyte reduced to a few cells; only gametes haploid | Seed plants (gymnosperms & angiosperms); alga Fucus |
| Haplo-diplontic | Both multicellular & free-living | One phase dominates the other | Bryophytes (gametophyte dom.) & pteridophytes (sporophyte dom.); Ectocarpus, Polysiphonia, Kelps |
