Bryophytes gametophyte dominant
WebMar 26, 2024 · Bryophytes are comprised of mosses, liverworts, and hornworts. These plants are primarily haploid gametophytes with a diploid portion attached to the plant consisting of the sporangium and stalk. They do not grow tall because they do not have any water-conducting tissues compared to vascular plants. WebApr 13, 2024 · Bryophytes: Bryophytes are non-vascular plants that lack true roots, stems, and leaves. They are the simplest and most primitive plants, typically found in moist environments. Mosses, liverworts, and hornworts are the three main groups of bryophytes. Bryophytes are small, and their life cycle is dominated by the haploid gametophyte stage.

WebThe completion of the bryophyte and pterophyte life cycle requires water because the male gametophyte releases sperm, which must swim—propelled by their flagella—to reach and fertilize the female gamete or egg. After fertilization, the zygote matures and grows into a sporophyte, which in turn will form sporangia or “spore vessels.” 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 …

WebBryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte.
