ANTHOPHYTA II. As in all plants, apart from the liverworts and mosses, the dominant phase of the flowering plant is the sporophyte. Click to see full answer
Also asked, which generation is dominant in Coniferophytes? Like the ferns and gymnosperms, angiosperms have a dominant sporophyte (2n) generation. Of the plants, angiosperms have the most dramatically reduced gametophytes with male (micro) gametophytes represented by a 3-celled structure and female (mega) gametophytes represented by a 7-celled structure. Secondly, why Sporophyte is dominant over Gametophyte? The union of two gametes during fertilization produces a diploid zygote, which divides mitotically to form a new sporophyte. Thus, in the higher (i.e., vascular) plants the sporophyte is the dominant phase in the life cycle, whereas in the more primitive nonvascular plants (bryophytes) the gametophyte remains dominant. In this manner, which generation is dominant in Anthophytes?
