Are Anthophyta Gametophyte dominant?
Content: 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? sporophyte
Are gymnosperms Gametophyte or Sporophyte dominant? Gymnosperms, like all vascular plants, have a sporophyte-dominant life cycle, which means they spend most of their life cycle with diploid cells, while the gametophyte (gamete-bearing phase) is relatively short-lived. Gametophytes, as with all heterosporous plants, develop within the spore wall.
