The life cycle in bryophytes is
Open in App
Solution
The correct option is D haplo-diplontic
Bryophytes exhibit haplo-diplontic life cycle as the gametophytic phase is prominent (60%) in their life cycle. Both the sporophytic and gametophytic generations are multicellular. The gametophyte is haploid, independent (photosynthetic) and produces gametes by mitosis. The sporophyte is diploid, dependent on the gametophyte for nutrition and produces spores by meiosis. The dominant multicellular gametophyte alternates with a short-lived multicellular sporophyte.
