Detailed explanation-1: -The gametophyte is the dominant life phase in the Bryophytes. The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively. Collectively these structures are known as gametangia.

Detailed explanation-2: -Gametophyte is a dominant phase in the life cycle of a bryophyte.

Detailed explanation-3: -The sporophyte is the diploid generation and the gametophyte is the haploid generation. In Bryophytes which are the nonvascular plants, the dominant phase is gametophyte. Riccia is a liverwort belonging to Bryophyta and hence shows a dominant gametophytic stage.

Detailed explanation-4: -The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte.

Detailed explanation-5: -The main plant body in Bryophyte is a haploid gametophyte.
