In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it.
It is important to note that the gametophyte is haploid and the sporophyte is dploid.
The sporophyte generation carries its chromosomes as doubles. ... The spores then develop into the gametophyte generation. In most plants, the gametophyte is tiny compared to the sporophyte. As its name implies, the gametophyte generationproduces sex cells - sperm and eggs.
the gametophyte stage begins with meiosis and the sporophyte stage begins with fertilization.
No,they usually look quite different
i thought they produce spores.
The sporophyte generation is the result of the fusion of gametes. :)
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
Basically, plants have two stages in their life cycle, they can appear as a gametophyte or a sporophyte.
gametophyte: The gamete-bearing individual or phase in the life cycle of a plant having alternation of generations sporophyte: The spore-producing individual or phase in the life cycle of a plant having alternation of generations
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.

spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.

sporophyte and gametophye. since plants have alternation of generation, both are multicellular (haploid and diploid)
In reference to the sporophyte and gametophyte, are the stages of the plant's life cycle thus being the same.
Two different forms a plant can have.
The Sporophyte stage and the gametophyte stage
