Question

What does happen in haplodiplontic life cycle?

Accepted Answer

The life cycle is a sequence of events that occur from birth to death of an organism. The different groups of organisms have different patterns of the life cycle. In haplodiplontic life cycle, two distinct multicellular phases are present, i.e., diploid sporophyte and haploid gametophyte. The diploid phase produces haploid spores by meiosis and these develop to form multicellular gametophytes. The sporophytes are developed from the fusion of gametes. These develop to form multicellular structures.

The bryophytes and pteridophytes possess this type of life cycle. In bryophytes, the dominant phase is gametophyte, it alternates with short-lived multicellular sporophyte which is partially or totally dependent on the gametophyte. In pteridophytes, the dominant phase is diploid sporophyte and it alternates with multicellular autotrophic, haploid gametophyte. This pattern represents haplodiplontic life cycle.
