(i) Haplontic Sporophytic generation is not prominent,
e.g., algae, etc.
- Topic – Plant lifecycles
- Haplo – Diplontic Both gametophytic (n) and sporophytic (2n) are free – living, independent and multicellular phases,
e.g., bryophytes, pteridophytes, etc.
- Topic – Plant lifecycles
- Diplontic Gametophytic generation is of very short duration,
e.g., gymnosperms and angiosperms, etc.
