The gametophytes produce both male and female gametes from the plant body through the process of mitosis. However, the sporophyte uses meiosis to produce haploid cells.

WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. What happens between these two events, however, can differ a lot between different organisms ... WebEach sporophyll is associated with one yellow to orange kidney-shaped sporangium. In several species the spores develop rapidly on the soil surface into ovoid-cylindrical …
Web12 Jun 2024 · These two life stages differ drastically in their morphology and physiology—fern sporophytes have true vascular tissue and are homoiohydric (i.e., they regulate their internal water content), whereas fern gametophytes are much smaller (often < 1 cm), lack vascular tissue, and are poikilohydric. Bryophytes (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. Because this embryo-nurturing feature of the life cycle is comm…

It remains attached to the gametophyte (the haploid mother), and is in fact, parasitic upon it. The sporophyte relies on the gametophyte to provide it with food and water, which are passed through transfer cells that lie in the placental layer between the gametophyte and the sporophyte. hoffen thesaurusWebSporophyte: The spore-producing phase of a plant’s life cycle is known as sporophyte. Plants reproduce in two stages: sexual and asexual reproduction. The alternation of generation separates these two phases into the sporophyte and gametophyte through the processes of meiosis and fertilisation. https domain forwarding godaddyWebMoss sperm are motile and capable of swimming short distances to fertilize an egg.
