The life cycle of nonvascular plants includes an alternation of generations between a gametophyte and a sporophyte. The gametophyte generation produces gametes (eggs and sperm) through mitosis, which then fuse to form a zygote that develops into the sporophyte generation through mitosis. The sporophyte produces spores through meiosis that develop into new gametophytes.
Is the gametophyte generation haploid or diploid?
yes, the gametophyte generation of a moss is haploid. While the sporophyte generation of a moss is diploid.
How does the gametophyte generation of a plant differ from the sporophyte generation?
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.
What generation is dominant in moss?
The dominant generation in mosses is the gametophyte generation. This is the photosynthetic, leafy structure that produces gametes for sexual reproduction. The sporophyte generation in mosses is much smaller and dependent on the gametophyte for nutrients.
What is the dominant generation of Bryophytes?
In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell.http://en.wikipedia.org/wiki/Vascular_plants

Which process occurs before the gametophyte generation?
What is the process that occurs before the gametophyte generation Edited answer: Sporogenesis in the sporophyte is the starting point for gametophytic generation to produce haploid spores.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
Is the gametophyte generation haploid or diploid?
yes, the gametophyte generation of a moss is haploid. While the sporophyte generation of a moss is diploid.

Is a sporophyte or gametophyte embryo in a seed?
In a seed, it is the sporophyte embryo that is present. The sporophyte is the diploid generation that develops from the fertilization of gametes, while the gametophyte generation is typically reduced and dependent on the sporophyte in seed plants. Thus, the seed contains the developing sporophyte embryo, which will grow into the mature plant.
What generation is dominant in moss?
The dominant generation in mosses is the gametophyte generation. This is the photosynthetic, leafy structure that produces gametes for sexual reproduction. The sporophyte generation in mosses is much smaller and dependent on the gametophyte for nutrients.
What is the difference between sporophyte and gametophyte?
Sporophyte is the diploid (2n) stage in the life cycle of plants that produces spores through meiosis, while gametophyte is the haploid (n) stage that produces gametes through mitosis. Sporophyte generation is dominant in vascular plants, while gametophyte generation is dominant in non-vascular plants like mosses and liverworts.
What is a primary sporophyte?
spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
Do non flowering plants have a life cycle?
Yes, non-flowering plants, such as mosses, ferns, and conifers, have a life cycle that typically includes both a sporophyte and a gametophyte stage. In these plants, the sporophyte generation produces spores, which grow into the gametophyte. The gametophyte then produces gametes that can fuse to form a new sporophyte, thus continuing the cycle. This life cycle can vary significantly among different groups of non-flowering plants.
Is sporophyte dominant in seed plants?
Yes, sporophytes are the dominant generation in seed plants. In these plants, the sporophyte is the larger, more complex structure that carries out photosynthesis and is responsible for reproduction. The gametophyte generation is reduced and often dependent on the sporophyte for nutrients and protection. This shift to a dominant sporophyte is a key characteristic of seed plants, distinguishing them from other plant groups like mosses, where the gametophyte is more prominent.
