what are 5 ways meiosis differs from mitosis?

Meiosis is a completely different process from mitosis.\n\nI should stop doing other people's homework...\n\nMeiosis ends with a different amount of cells, and the cells as a result of meiosis only have 1/2 of the chromosomes of the original cell, where in mitosis, the daughter cells have the same amount of chromosomes.\n\nIn meiosis, there are two divisions. \n\nMeiosis occurs only in reproductive cells. For example, in humans, sperm has 23chromosomes and eggs have 23 chromosomes, a normal human cell has 46, which is why it takes two reproductive cells to create a living thing.\n\nI could go on and on, but I have to return to my own work.

1- Meiosis happens in stem cells that give rise to gametes (sex cells). \nMitosis happens in all other cells.\nIn women every month only one stem cell goes through meiosis forming 4 haploid cells. In men many cells go through meiosis everyday.\nEvery other cell in body goes through mitosis in a daily basis to replace old and dead cell.\n2- Before cell replication starts.\n3- At the end of the prophase (in case of meiosis, end of the prophase 1)\n4- Mitosis: diploid cells; Meiosis: haploid cells\n5- Every thing but cell division: the cell obtain nutrients and when it gets close to cell division, it will duplicate its DNA and other organelles.

It is definitely the chromosomes that divide in both mitosis and meiosis. However, the whole cells divides so # 1 sounds like the right answer. Did you ask in class? I am glad you are asking here , but you really should ask your teacher.

Mitosis is when a cell divides into to identical daughter cells. They contain the same genome as the parent cell. The only way a daughter cell can be altered is through a mutation of DNA/RNA.

>meiosis (mīŏ'sĭs) , process of nuclear division in a living cell by which the number of chromosomes is reduced to half the original number. Meiosis occurs only in the process of gametogenesis, i.e., when the gametes, or sex cells (ovum and sperm), are being formed. Because fertilization consists of the fusion of two separate nuclei, one from each of the sex cells, meiosis is necessary to prevent the doubling of the chromosome number in each successive generation. An ordinary body cell is diploid; i.e., it contains two of each type of chromosome. The members of each pair are known as homologous chromosomes. An ovum or sperm is haploid; i.e., it contains only a single chromosome of each type and, therefore, half the number of chromosomes of the diploid cell. When the two haploid cells fuse, the diploid number is restored, and the plant or animal growing from the fertilized egg (zygote) has the usual diploid number of chromosomes in its cells. Just before meiosis each chromosome replicates to form two identical copies in the form of strands called chromatids joined together at a point called the centromere. In the first stage of meiosis, called the reduction division, the members of each pair of homologous chromosomes lie side by side and crossing over occurs. Each member of the pair then moves away from the other toward opposite ends of the dividing cell, and two nuclei, each with the haploid number of double-stringed chromosomes, are formed. Thus at the beginning of the second meiotic sequence, called the equational division, each cell nucleus contains one chromosome from each homologous pair and each chromosome is of two strands that are identical (except where crossing over has occurred). Then the chromosomes separate into their single strands which move toward opposite ends of the dividing nucleus. The result of meiotic division is four cells, each haploid, with one chromosome of each pair.\n\n>meiosis (meye-oh-sis) \nDivision of cells in which four “daughter” cells are produced from one “parent” cell, each with half the genes of the parent. Meiosis is a key process in sexual reproduction. In the ovaries and testes, meiosis produces a great variety of sex cells (sperm and ova), because the genes of the parent cell can be split in many different ways. The sex cells combine in fertilization to produce a new individual with the full number of genes — half from each parent. Because the sex cells come in such variety, and come from two parents, there is an enormous number of possible forms for the offspring. (See chromosomes, genetics, and mitosis.) \n\n>mei·o·sis (mī-ō'sĭs)\nn., pl. -ses (-sēz').\nThe special process of cell division in sexually reproducing organisms that results in the formation of gametes, consisting of two nuclear divisions in rapid succession that in turn result in the formation of four gametocytes, each containing half the number of chromosomes that is found in somatic cells.\n\n>meiosis: \nIn biology, meiosis is the process that transforms one diploid cell into four haploid cells in eukaryotes in order to redistribute the diploid's cell's genome.\n\nMeiosis forms the basis of sexual reproduction and can only occur in eukaryotes. In meiosis, the diploid cell's genome, which is composed of ordered structures of coiled DNA called chromosomes, is replicated once and separated twice, producing four sets of haploid cells each containing half of the original cell's chromosomes. These resultant haploid cells will fertilize with other haploid cells of the opposite gender to form a diploid cell again. The cyclical process of separation by meiosis and genetic recombination through fertilization is called the life cycle. The result is that the offspring produced during germination after meiosis will have a slightly different blueprint which has instructions for the cells to work, contained in the DNA. This allows sexual reproduction to occur.\n\nBiochemically

meiosis is the production of sex cells. \nmitosis is the production of somatic (body - think skin cells) cells.\n\nMitosis occurs in 5 stages - interphase, prophase, metaphase, anaphase and telophase. \n\nInterphase = is when the DNA condenses into chromatin and gets ready for replication. This is the stage when the DNA replicates itself.\n\nProphase = is when spindle fibers form, the chromosomes condenses, the nuclear membrane breaks down and the cell begins to get ready to divide. \n\nMetaphase =  is when the chromosomes line up in the middle of the cell. \n\nAnaphase =  is when the chromosomes move away from the middle and to the ends of the cell\n\nTelophase = two new nuclear membranes form.\n\n*Cytokenis = not really a stage, but it's when the cells organelles split. At the end of mitosis, you have two new somatic cells.\n\nMeiosis is trickier. there's a Meiosis I and Meisosis II. basically diploid cells are split in half to form haploid cells. \n\nMeiosis I is made up of Interphase, Prophase I, Metaphase I, Anaphase I, and Telophase I. Each of those stages are mostly the same as Mitosis, except that at the end of Meiosis I, you have 2 new daughter cells. \n\nMeiosis II is made up of Prophase II, Metaphase II, Anaphase II and Telophase II. these stages are the basically the same as mitosis too except that at the end of Meiosis II, you have 4 new daughter cells (that are haploid, meaning they have one set of chromosomes.)\n\nthis is just what i remember from biology. you should google it if you want more details.

meiosis ensures that each gamete is a haploid (i.e. has half, or n, chromosomes of a normal cell). when the gametes fuse the zygote becomes 2n like a normal cell. Mitosis produces daughter cells which both have 2n, and these cannot be present in the gametes or else the zygote would have 4n!

Meiosis occurs after sexual maturity in both male and females.\nIn males in happens almost all the time after maturity, as males need to produce millions of sperm.\nIn females it happens approximately once a month and happens much more slowly, producing one gamete (egg or oocyte) for use.

Meiosis II is the second part of the meiotic process. Much of the process is similar to mitosis and meiosis I. \n\nProphase II \nIf needed, the nuclear membrane and nuclei break up while the spindle "network" appears and the chromosomes begin migrating to the metaphase II plate (at the cell's equator).\n\nMetaphase II \nThe chromosomes line up at the metaphase II plate at the cell's center. The kinetochores of the sister chromatids point toward opposite poles.\n\nAnaphase II \nThe sister chromatids separate and move toward the opposite cell poles.\n\nTelophase II \nDistinct nuclei form at the opposite poles and cytokinesis occurs.\n\nAt the end of meiosis II, there are four daughter cells each with one half the number of chromosomes of the original parent cell.

The purpose of both mitosis and meiosis is to take one cell and make two cells. Before the cells do this though, they have to make sure that a few things are in order. Obviously, there has to be enough stuff for the 2 cells to each be able to live independently. so, there has to be duplication of a lot of stuff before the first cell (let's call it the parent) divides. One of these things is the genome. These are the chromosomes which are made up of DNA. Once the DNA replicates (makes 2 copies of everything from what the parent originally had), the cell can divide. There are now 4 chromosomes of each type, we started out with our usual 2 of each (most organisms have 2 of each chromosome and they differ slightly from each other-this becomes important for meiosis), then when everything duplicated, we got 4! \n\nIn MITOSIS, the 2 cells that come out of the division (lets call them the daughters), are EXACTLY the same in genetic makeup as the original mother cell. They have the very same DNA and therefore make the same proteins and therefore the cells behave the same. \n\n In MEIOSIS on the other hand, the cells are not the same at all. And in fact, this is the point of meiosis - to make new types of cells. You may know that eggs and sperm are products of meiosis, but you not only get a mixing of genes from your mother (from the egg) and father (from the sperm), but the genes inside the egg and sperm are pre-mixed because of meiosis. Thus, genetic diversity!, and an explanation for why you have traits given to you from your grandmother through your father, even though your father may not have that trait (he carries it in his genes for later mixing). This may be a complicated issue in itself but since we have 2 of every chromosome and therefore 2 of every gene (even before the DNA replication that preceeds mitosis), there's a chance that the 2 copies of the same gene are different, one of which shows up in your father and one which you have that you got from your grandmother throuh your father. The mixing, by the way comes about because after the DNA replicates in preparation for cell division. This is neat and involves chromosomes breaking apart and joining back together. Take a look at the animated movie of meiosis at http://www.biology.yale.edu/animatedMeiosis.nclk - make a point to notice the red and green chromosomes at the beginning and the mixed ones at the end.
