in bryophytes the sporophytes is diploid(2n) while the gametophyte in bryophytes is haploid(n).In bryophytes the sporophytes are totally or partially dependent on gametophytes while gametophytes are the dominant generation in bryophytes.Male sporophytes produce male spores and that of female produce megaspores of female spores while male gametophytes produce male gametes while female gametophytes produce female gametes
What else can I help you with?
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
Why gametophyte is dominant in baryophytes?
In bryophytes, the gametophyte generation is dominant because it is the stage that is more prominent, photosynthetic, and capable of independent growth. This generation develops from spores and produces gametes through mitosis, allowing for sexual reproduction and genetic diversity. The sporophyte, which arises from the fertilization of gametes, is typically dependent on the gametophyte for nutrition and support, making the gametophyte the more prominent and vital stage in the life cycle of bryophytes.
Which plant phyla have a dominant sporophyte generation?
In the plant kingdom, the phyla that have a dominant sporophyte generation include the Angiosperms (flowering plants) and Gymnosperms (non-flowering seed plants). Additionally, the vascular plants, such as Ferns (Pteridophyta), also exhibit a dominant sporophyte stage, although the gametophyte is more independent compared to those in non-vascular plants. In contrast, in non-vascular plants like Mosses (Bryophyta), the gametophyte generation is dominant.
What is the dominant generation of division cycadophyta?
The dominant generation of division Cycadophyta is the sporophyte generation. This generation is the main phase of the plant's life cycle and produces spores that give rise to the next generation of plants. The sporophyte is typically larger and longer-lived than the gametophyte generation.
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.
Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.
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 plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
What is a primary sporophyte?
spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
Does gametophyte generation depends on sporophyte generation in ferns?
Yes, in ferns, the sporophyte generation is dominant and produces spores that give rise to the gametophyte generation. The gametophyte generation is a smaller, independent stage that produces gametes (sperm and egg) which fuse during fertilization to form the sporophyte generation.
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

How does the sporophyte generation of a plant differ from a gametophyte 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.
Which generation in the Phylum Bryophyta is the most conspicuous?
The gametophyte generation is the most conspicuous in the Phylum Bryophyta. Gametophytes are the dominant and noticeable stage in the life cycle of mosses, liverworts, and hornworts, while the sporophyte generation is typically smaller and less noticeable.
