Mitosis is the reproduction of somatic (body) cells, while meiosis is the production of gametes (sex cells).\n\nThe normal cell has a chromosome number of "2n".  For example, a fruit fly has a chromose count of 8, so 8=2n.\n\nFollowing so far? Good.\n\nMitosis:\nMitotic division begins with a cell in Interphase, with a chromosome count of 2n.\nThe chromosomes are not visible right now under the microscope, they just look like a mass of tangled string called chromatin.\n\nIn Prophase, the chromosomes replicate, but remain attatched to their partner by a centromere (kinda look like an x).  Spindle fibres form and the centrioles migrate to the ends of the cell, opposite each other.  Nuclear membrane disappears.\n\nIn Metaphase, the chromosomes line up on the equatorial line (a bunch of x in a row along the middle of the cell), and spindle fibres attatch to each chromatid in the pair (right now, the two parts to the x are individually chromatids, but are together a chromosome).\n\nDuring Anaphase, the spindle fibres pull each daughter chromosome so that the pair of chromatids splits apart and half of them go to one end of the cell, and half to the other.\n\nDuring Telophase, the nucleolus forms and the nuclear membrane forms around the two sets of chromosomes.  A clevage furrow separates the cell into two daughter cells, each having a 2n number of chromosomes.\n\nPhew.  Still following?  Good- that was just Mitosis!\n\nNow for the fun one.  Meiosis.\nMeiosis takes the 2n cell and turns it into FOUR  (4) gametes.\nIn your body, each individual chromosome is part of a homologous pair.  That is, each has a match.  This is why we represent the chromosome number as 2n- There are two sets of n chromosomes.  In our fruit fly, the 2n number is 8, so there are 4 sets of homologous pairs.  Following? Good.\n\nMeiosis in the fruit fly begins with a single cell with 8 chromosomes, and ends with 4 cells with 4 chromosomes each.\n\nWhy does it end with "n" instead of "2n"?  Each gamete provides half the genetic information needed to create the new organism.  You get half your genes from your mother and half from your father.\n\nAnyway, meiosis takes place in two stages: aptly called meiosis 1 and meiosis 2.\n\nMeiosis 1:\nIn Interphase, the cell has roughly the same appearance as it did in Interphase of Mitosis.\n\nIn Prophase 1: The chromosomes duplicate and find their homologous pairs.  Now, the little groups istead of looking like an x, look like an x with four little lines joining, because there are 4 chromatids attached together, called a tetrad.  Understand?  I hope so!\nAt this point, the two chromatids nearest together in the tetrad may "cross over".  In other words, they swap genetic information.  Homologous pairs carry similar, but not identical coding (remember one was from your father, one from your mother).  In this way, you now have 4 chromatids that are each unique in their coding, which allows for genetic variation!  \nCentromers go to opposite ends, and spindle fibres begin to form.  Nuclear membrane disappears\n\nIn Metaphase 1: The tetrads line up on the equatorial line (remember this?)  The spindle fibres attatch to each side of the tetrad.\n\nIn Anaphase 1: The spindle fibres split the tetrads in half, so that 2 chromatids (1 chromosome now) go to one pole of the cell, and 2 chromatids (1 chromosome) go to the other.\n\nIn Telophase 1: The nuclear envelope/membrane reappears around each set of chromosomes, and a cleavage furrow splits the cell into two daughter cells.\n\nAt this point, we now have two daughter cells with "n" for the chromosome count, because there is half the amount of chromosomes we had when we started!\n\nOk, now each daughter cell undergoes meiosis 2, so that at the end we have 4 gametes.\n\nProphase 2:  Nuclear envelope dissappears.  Centroles migrate to the opposite sides of the cells, spindle fibres form.  Remember that the chromosomes are composed of

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 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\nMeiosis uses many biochemical processes that are similar to those used in mitosis in order to distribute chromosomes among the resulting cells; however the outcome is very different.

Mitosis produces two cells which are genetically identical to the original one. There is no exchange of genes between two organisms, and so mitosis is a type of asexual reproduction.

Most mitotic cell divisions do result in daughter cells that are equal in size to the parent. During interphase, the cellular material, like cytoplasm, is duplicated as well as the genetic material. This is not the case for meiotic cell divisions, though, which yield cells that are certainly smaller than the parents, about 1/4 the size, and it is not always the case in mitosis, like for example, in the developing blastula.

During *mitosis*, the cytoplasm of a cell and its organelles separate into two new *identical cells*?\n\nI'm not sure what else you're looking for here...

The products of mitosis are 2 genetically identical daughter cells and the products of meiosis II 4 genetically dissimilar haploid cells.  Meaning these cells only have half the amount of chromosomes of the parent cell and these chromosomes are genetically unique, even between each other.  Pretty cool huh?  This is the explaination for everyone being genetically unique!

Meiosis is also known as reduction division.\nIt is a type of nuclear division that gives rise to four reproductive cells (gametes) each with half the chromosome number of the parent cell. Two consecutive divisions occur. In the first, homologous chromosomes become paired and may exchange genetic material before moving away from each other into separate daughter nuclei. This is the actual reduction division because each of the two nuclei formed contains only half of the original chromosomes. The daughter nuclei then divide by mitosis and four haploid cells are produced. Four stages, prophase, metaphase, anaphase and telophase\n\nMitosis is a type of nuclear division that results in two daughter cells each having a nucleus containing the same number and kind of chromosomes as the mother cell. each chromosome divides lengthwise into two chromatids, which seperate and form the chromosomes of the resulting daughter nuclei. Four stages as well prophase, metaphase, anaphase and telophase, which merge into each other. Mitotic divisions ensure that all cells of an individual are genetically identical to each other and to the original gertilized egg.

Mitosis:\n\nOccurs during cell division of somatic cells\n\nA full set of chromosomes is passed on to each daughter cell. This s the diploid number of chromosomess\n\nthe choromosomes and genes in each daughter cell are identical.\n\nIf new organisms are produced by mitosis is asexual reproduction they will all resemble each other and their parents. they are said to form a 'clone'.\n\n\nMeiosis;\n\nOccurs in the final stages of cell division leading to production of gametes.\n\nOnly half the chromosomes are passed on to the daughter cells, i.e. the haploid number of chromosomes.\n\nThe homologous chromosomes and their genes are radomly assorted between the gametes.\n\nNew organisms produced by meiosis in sexual reproduction will show variations from each other and form their own parents.

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: -- One cell becomes 4 cells--There are 4 new "daughter" cells. Each new gamete cell contains only one-half of the number of chromosomes of the parent cell. Each sex cell goes through the division process twice in order to have the correct number of cells, and the correct chromosomal information.\n\nMitosis: -- One cell becomes two cells-- The new "daughter" cell has exactly the same number of chromosomes and information as the "parent" cell. 1 cell divides and becomes 2 cells.

Cytokinesis isn't truly mitosis or interphase, but a stage of it's own. It happens at the end of mitosis and is often included in explanations of mitosis.

cytokinesis is the process of splitting of cell in two by forming a cleavage on its cytoplasm while karyokinesis is forming of cleavage in the nucleus...?? oh!not sure..hehe..

mitosis is the normal mode of cell multiplication and increasing there number without a change in their constiution so it occurs in all the SOMATIC CELLS (normal cells of body not involved in sexual reproduction).\nmeiosis occur in gamete forming cells as it is the reductoinal division

Mitosis is the formation of identical daughter cells, it has nothing to do with the interacting of "two" cells.  Plant cells have a different pinching off process when the one cell becomes two because of the cell walls.  Also animal cells have a structure called centrioles that does something in mitosis but I do NOT remember what it does...

two cell divisions.... one for meiosis 1 and one for meiosis 2
