How do the two alternating generations of the plant life cycle differ?
In plants, the two alternating generations are the sporophyte (produces spores) and the gametophyte (produces gametes). The sporophyte is usually diploid, while the gametophyte is haploid. The sporophyte is usually larger and more dominant than the gametophyte.
How does the gametophyte generation of a plant differ from the sporophyte generation?
The gametophyte generation produces gametes (sex cells) through mitosis and is haploid (1 set of chromosomes), while the sporophyte generation produces spores through meiosis and is diploid (2 sets of chromosomes). The gametophyte is typically smaller and structurally simpler compared to the sporophyte.
Why do gametophytes die after the sporophyte starts to grow?
Gametophytes die after the sporophyte starts to grow because their purpose is fulfilled. The gametophyte produces gametes that combine to form a new sporophyte, which will become the dominant generation in the plant life cycle. Once the sporophyte is established and able to produce its own spores, the gametophyte is no longer needed and naturally senesces and dies.
Summarize the process of alternation of generations?
The alternation of generations is a reproductive cycle where plants alternate between a multicellular haploid (gametophyte) and diploid (sporophyte) phase in their life cycle. The gametophyte produces gametes through mitosis, which fuse to form a diploid zygote. The zygote then develops into a sporophyte through mitosis, which produces spores through meiosis, starting the cycle anew.
What is sporophy?
Sporophyte is the diploid (2n) stage of the plant life cycle. It is the multicellular spore-producing organism that develops from the zygote of a fertilized egg. The sporophyte is typically the primary photosynthetic form of the plant and is responsible for the production of spores. It is the stage of the plant that produces the spore-bearing structures such as the antheridia and archegonia which in turn produce the haploid gametes that are necessary for sexual reproduction.The sporophyte stage of the plant life cycle includes the following main components:Cellular growth and developmentProduction of haploid gametesSpore formationGrowth and maturation of sporophyte structuresThe sporophyte stage of the plant life cycle typically dominates the life cycle of most plants and is responsible for the growth and development of the plant. It is the main photosynthetic form of the plant and is responsible for producing the haploid gametes that are necessary for sexual reproduction.
In the sporophyte stage what do plants produce?
spores
What do plants produce in sporophyte stage?
spores
Sexual reproduction in sponges produce an organism are called?
Sporophyte
In flowering plants the sporophyte does what?
Flowering plants do not have a sporophyte. They have antheridium and archegonium to produce their gametes. Sporophyte is found in ferns, mosses, club mosses, lycophytes, etc but not in flowering plants. Flowering plants produces pollen while a sporophyte produces spores
Do maple trees have leaves?
The maple trees that you see are in the sporophyte stage of the plant life cycle. A sporophyte will produce spores which then develop into gametophytes. So, yes, maple trees have spores (if you are talking about the sporophyte stage). The sporophyte stage is part of the life cycle of all land plants.

Which stage in the alternation of generations life cycle would fern represent?
A fern would represent the diploid sporophyte stage in the alternation of generations life cycle. This is the dominant stage in ferns where sporophyte plants produce spores through meiosis.
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.
What is the second generation produce in mosses?
Second generation produced in mosses is sporophyte on the gametophytic plant body.
Why is the seta and capsule known as the sporophyte generation?
The seta and capsule are known as the sporophyte generation because they are structures that produce spores through meiosis, which will ultimately give rise to the gametophyte generation. The sporophyte generation is diploid, meaning it contains two sets of chromosomes, whereas the gametophyte generation is haploid, containing one set of chromosomes.
