Answer 2

$\huge{Answer:}$

$Haplo-Diplontic\:Life\:Cycle:-$

1) It is an intermediate type of life cycle, where both the sporophyte and gametophyte are multicellular, equally dominant and often free-living. Bryophytes and pteridophytes exhibit this pattern.

2) In Bryophytes, the dominant phase is the independent, photosynthetic, thalloid or erect haploid gametophyte and it alternates with the short-lived multicellular sporophyte totally or partially dependent on the gametophyte for its anchorage and nutrition.

3) In pteridophytes, the dominant phase is represented by the sporophyte which is diploid, independent, photosynthetic vascular plant body. It alternates with multicellular, independent but short-lived haploid gametophyte.

4) Algae exhibit haplontic life cycle but some of them such as Ectocarpus, Polysiphonia, Kelps are haplo-diplontic.
