The typical "fern" plant the, sporophyte, is diploid.
For this Q'n the A. is that 'no such' system exists. Meiosis produces haploid gametes in all Eukaryotic Cells. For an application of diploid chromosomes see Mitosis.
Anaphase of Meiosis 1 separates the homologous chromosome pairs, but during Anaphase of Meiosis 2, the sister chromatids are separated instead. Also, Meiosis 1 starts with one diploid cell and ends with 2 haploid cells, whereas Meiosis 2 starts with the 2 haploid cells and ends with 4 haploid cells (gametes).
Actually cucumbers have eight-teen chromosomes
A diploid is an organism with a 2n genome. that means every gene is encoded twice, the 2 genes could be exactly the same or different (alleles) most animals and plants you see are diploid.
The brown things underneath the leaf of a fern plat are spores.They a reproductive cells that blow away to plant new plants.They are on every leaf you see

Unfertilized egg is haploid; but fertilized egg is diploid. That is why you sometimes see chickens even in commercial eggs.
Okay, so a pigeon has 80 chromosomes when its cells are in the diploid stage. In the haploid stage the cells have 40 chromosomes.
The small, greenish heart-shaped structure or gametophyte (n-haploid) of a fern that produces the male and female gametes for fertilization and spore formation which leads to the development of the sporophyte generation--(2n-diploid) -->the plant you see above ground is the sporophyte generation.
Meiosis takes place in diploid cells. These are cells which have pairs of chromosomes. For example, in humans there are 23 pairs of chromosomes in the body cells. During meiosis the number of chromosomes is halved, so that haploidcells are produced. These are cells with only one chromosome from each pair. So in humans haploid cells contain 23 singlechromosomes. The haploid cells produced in humans (and other animals) are the sex cells or gametes. These are the sperm cell in males and the egg cell in females. When fertilization takes place the gametes fuse and the diploid number of chromosomes is restored. So the simple answer to your question is egg cells and sperm cells (in humans and other animals). For details of meiosis see http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/M/Meiosis.html However in plants the situation is slightly different. Here meiosis produces haploid spores which germinate to produce a haploid sporophyte. The sporophyte produces gametes by mitosis.

I think what you are asking is "What are the two distinct processes of meiosis?"At the beginning of meiosis, there is a diploid cell (chromosomes come in pairs) with duplicated chromosomes (each pair of chromosomes is duplicated). The cell undergoes two processes: Meiosis I and Meiosis II.Meiosis I produces two haploid cells (unpaired chromosomes), but the chromosomes are still duplicated. These two cells then undergo Meiosis II, in which the two haploid cells are split, with one set of unpaired chromosomes going to one and the other set of unpaired chromosomes to the other. The end result of Meiosis II is four haploid cells with unduplicated chromosomes.In short, when a cell undergoes the complete process of meiosis, a single diploid cell with duplicated chromosomes is turned into four haploid cells with unduplicated chromosomes.For a complete description of all the steps along the way, see this page and scroll down about 2/3 of the way: http://en.wikibooks.org/wiki/Adventist_Youth_Honors_Answer_Book/Health_and_Science/Heredity

A transverse section of the anther reveals four areas of tissue capable of producing spores. These tissues are composed of microsporocytes, which are diploid cells capable of undergoing meiosis to form a tetrad (four joined cells) of haploid microspores. The microspores become pollen grains and may eventually separate.

Fern is multicellular bcz we cant see unicellular organisims and we can see multicellular organism.U now that we can see a fern so t means it is unicellular.from pakistanschool name Joan Mcdonald Schoolwritten by a girl (cant tell u name)
