Question

What is the dominant phase in bryophytes is it gametophyte or sporophyte

Answer 1

Gametophyte.
In Bryophytes, haploid gametophyte is dominant, independent, and photosynthetic. It alternates with short-lived multicellular sporophyte totally or partially dependent on gametophyte for nutrition and anchorage.

Sporophyte is the phase in life cycle of plants which is diploid (means cells contain two sets of chromosomes). Sporophyte produces haploid spore through meiosis. Spores germinate into haploid plants also called haploid gametophytes. Gametophytes produces gametes.

Bryophytes show haplodiplontic cycle which is an intermediate condition of haplontic and diplontic life cycles. Both gametophytic (haploid) and sporophytic phases(diploid) are multicellular and often free-living.
