Gametophytes are diploid or haploid
WebDec 3, 2024 · Gametophytes occur in the haploid stage of life, while the sporophytes occur in the diploid stage. The gametophytes are leaf-like and use the process of photosynthesis to make food for the plant. WebJun 8, 2024 · The haploid multicellular plants are called gametophytes because they produce gametes from specialized cells. Meiosis is not directly involved in the production of gametes because the organism that produces the gametes is already a haploid. Fertilization between the gametes forms a diploid zygote.

Plants have an alternation of generations when...
Web8. Ferns are the plants in which the haploid spores do not leave the diploid plant body and, instead, form gametophytes within the sporophyte. Ferns are a type of seedless vascular plant that reproduces via alternation of generations, meaning that they have both haploid and diploid stages in their life cycle. WebMay 3, 2024 · The male gametophyte produces spermatangia at the tips of its branches and these spermatangia produce haploid spermatia by mitosis. The female gametophyte produces carpogonial branches, which have an egg at the base and a long filament called a trichogyne that extends from the egg chamber.
WebBoth the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and … WebApr 11, 2024 · Therefore, most of these studies have compared male gametophytes, typically pollen-expressed genes, to genes expressed in sporophytic tissues. Results of …
WebThe gametophytes are much smaller than sporophytes and are produced within flowers. Pollen grains are haploid, sperm-producing structures and therefore represent the male gametophyte (or microgametophyte). Embryo sacs are haploid, egg-producing structures which constitute the female gametophyte (or megagametophyte).
WebThe sporangium in the ovary (where the female gametophyte will be formed) is called the megasporangium. Diploid microspore mother cells in the microsporangium and diploid megaspore mother cells in the megasporangium divide by meiosis to form four haploid micro- or mega- spores. These spores initiate the gametophyte phase. kids school in seattleWebDiploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte. Mitotic divisions within the gametophyte are required to … kids school items onlineWebAnswer:-.
