Does gametophyte produce zygote?
The gametophyte stage produces gametes (by mitosis) which fuse to form a zygote. The zygote divides by mitosis to form the large multicellular sporophyte stage.Mar 5, 1998
What does gametophyte produce?
The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively. Collectively these structures are known as gametangia.
What do gametophytes produce in plants?
The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which has a double set of chromosomes.
What mitosis do gametophytes produce?
Male gametophytes develop reproductive structures called antheridia (singular, antheridium) that produce sperm by mitosis. Female gametophytes develop archegonia (singular, archegonium) that produce eggs by mitosis.
What does the gametophyte produce through mitosis or meiosis?
The gametophyte stage produces gametes (by mitosis) which fuse to form a zygote. The zygote divides by mitosis to form the large multicellular sporophyte stage. Mitosis and meiosis in Ferns (continued). The sporophyte produces haploid spores by meiosis.Mar 5, 1998
Is zygote a sporophyte or gametophyte?
The zygote is the first cell of the next generation of sporophyte. The zygote begins to divide to produce a multicellular sporophyte embryo. The embryo is an immature sporophyte that is nourished (fed) by the gametophyte.Jun 13, 2020
Is a zygote a sporophyte?
The zygote is the first cell of the next generation of sporophyte. The zygote begins to divide to produce a multicellular sporophyte embryo. The embryo is an immature sporophyte that is nourished (fed) by the gametophyte. Eventually, as the sporophyte grows, it will be able to sustain itself.Jun 13, 2020
Is a zygote a gametophyte?
A haploid spore germinates and begins to divide by mitosis to form the small multicellular gametophyte stage. The gametophyte stage produces gametes (by mitosis) which fuse to form a zygote.Mar 5, 1998
What is an example of a sporophyte?
The sporophyte of mosses such as Funaria and Polytrichum is formed after fertilization. The sporophyte of mosses consists of the foot, seta, and capsule. The capsule contains the haploid spores which on dispersal by wind form the gametophyte i.e antheridia and archegonia.
How does a zygote become a sporophyte?
Life cycle
The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.
What process makes sporophytes?
Diploid 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 produce the gametes. The diploid sporophyte results from the fusion of two gametes.
