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.
Can flowering plants reproduce by spores?
Yes the spores are like seeds. They drop off of a fern and onto the ground and sooner or later they sprout and makes a new fern. Spores are not like seeds. They lack a seed coat, endosperm and preformed embryonic parts. In addition spores give rise to the gametophyte generation and seeds give rise to the sporophyte generation. Ferns and mosses do both reproduce by using spores BUT mosses have a reduced almost parasitic sporophyte generation which produces the spores. These spores will produces the gametophyte generation (the green leafy thing we see). The gametophyte produces the sex cells that fuse to make a zygote. This zygote then forms a new sporophyte. With ferns the sporophyte generation is more dominant than the gametophyte. The leafy structure we see is the sporophyte.
What are the two stages of plant life?
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.
What is the name given to the life cycle of plants which includes a sporophyte generation and a gametophyte generation?
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.
Are the spores produced by the moss sporophyte formed by meiosis or mitosis?
The Gametophyte stage

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 is the difference between sporophyte and gametophyte?
Sporophytes reproduce with spores, while gametophytes reproduce sexuallyOf the two, it is the gametophyte is larger than the sporophyte.
Name and describe the three main stages in a plants life cycle?
Alteration of generations Sporophyte is 2n generation Meiosis produces spores Gametophyte is n generation
What process accomplishes the change from sporophyte to gametophyte?
It produces spores.
What types of algae show a distinct alternation of generations?
Some types of algae that show a distinct alternation of generations are members of the green algae group, such as Ulva and Spirogyra. These algae have a haploid gametophyte generation and a diploid sporophyte generation. The gametophyte generation produces haploid gametes that fuse to form a diploid zygote, which develops into the sporophyte generation that produces haploid spores.
What is the male gametophyte of a pine tree?
A pine tree is generally a Sporophyte - a multicellular, diploid, spore-producing organism. However, the created spores are haploid, and thus begin the gametophyte phase, in which the microspores (pollen) and megaspores (female receptors), will combine back into a gamete, and begin the sporophyte stage again.
What forms from a gametophytes?
A spore. The gametophyte makes gametes, which fertilize to form a zygote. That zygote develops into a sporophyte, which makes spores through meiosis. Those spores will then develop into the gametophyte.
