The "dominance" over the other phase can be seen in the following ways: The gametophyte organism depends on its …
WebThe gametophyte generation is dominant, conspicuous and independent. The female sex organ is the archegonium. The male sex organs are antheridia. The ovum remains in the archegonium and spermatozoids … WebIn bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant.

WebThe short, blue-green gametophyte is the dominant phase of the lifecycle of a hornwort. The narrow, pipe-like sporophyte is the defining characteristic of the group. The sporophytes emerge from the parent gametophyte and continue to grow throughout the life of the plant (Figure 4). Stomata appear in the hornworts and are abundant on the sporophyte. WebThe dominant part of the plant body is gametophyte which is haploid The thalloid gametophyte is differentiated into rhizoids, axis and leaves The gametophyte bears multicellular sex organs and is photosynthetic The antheridium produces antherozoids, which are biflagellated The shape of an archegonium is like a flask and produces one egg
