Detailed explanation-1: -Bryophytes show alternation of generation between independent gametophyte with sex organs, which produces sperm and eggs and dependent sporophyte which contains spores. The dominant part of the plant body is gametophyte which is haploid.
Detailed explanation-2: -Thus, the gametophyte stage is dominant in the more primitive (nonvascular) plants (bryophytes), whereas the sporophyte is the dominant phase in the life cycle of higher (i.e., vascular) plants. In algae, the dominant phase often depends on environmental conditions, though some species have determinant life cycles.
Detailed explanation-3: -In bryophytes, sporophyte is dependent on gametophyte.
Detailed explanation-4: -Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.
Detailed explanation-5: -The bryophytes show an alternation of generations between the independent gametophyte generation, which produces the sex organs and sperm and eggs, and the dependent sporophyte generation, which produces the spores.
