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.
What is a gametophyte?
A gametophyte is an organism in the life cycle of a plant that produces haploid gametes. It is the sexual phase of the plant life cycle and is the first stage in the alternation of generations between the gametophyte and sporophyte generations. The gametophyte produces male and female gametes, which are haploid cells that fuse to form a diploid zygote. The zygote develops into the sporophyte generation, which produces haploid spores that divide to form the next generation of gametophytes.
Is the gametophyte the dominant generation?
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
Why is it beneficial to have the sporophyte generation dominant in vascular plants?
One possible reason that stands out is that the sporophyte phase has anadvantage over the gametophyte phase because it is diploid rather than haploid.Having two sets of genes can avoid expression of deleterious traits.The seed plant pattern of large sporophyte is a very effective system. Rememberthe key features:1. Large sporophyte nurtures the tiny female gametophytes.2. There are millions of tiny male gametophytes (pollen) that can be carriedgreat distances, either by wind or by animals.3. New sporophytes arise from very mobile, usually very tough, seeds thatcontain energy supply and tiny plant in suspended animation.
What is larger then an atom?
pretty much everything is larger than an atom.

Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
Does the gametophyte of ferns depends on sporophyte generation?
The sporophyte of a fern, destined to grow to be magnitudes larger than the prothallium, destroys the prothallium as it grows.

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.

Is the sun much larger than all the other stars?
No. The sun only appears much larger than other stars because it is much closer. Many stars are much larger than the sun.
