what is the diffrence between Mitosis and meiosis?

Both previous answers are inaccurate.\n\nMitosis is sometimes called growth division. In plants and animals new cells are made continually. Mitosis results in two new cells identical genetically to the original which divided.\nWe are diploid animals which have 23 pairs of chromosomes. After mitosis both cells still have 23 pairs of chromosomes.\n\nMeiosis is a division which produces sex cells (sperm or ova). After division is complete, each sex cell has half the number of chromosomes; it is haploid. So instead of having 23 pairs the sex cells will have 23 chromosomes - one of each type of chromosome.

From Wikipedia, the free encyclopedia:\nMitosis divides genetic information during cell division. A cell in early anaphaseMitosis is the process by which a cell separates its duplicated genome into two identical halves. It is generally followed immediately by cytokinesis which divides the cytoplasm and cell membrane. This results in two identical daughter cells with a roughly equal distribution of organelles and other cellular components. Mitosis and cytokinesis together is defined as the mitotic (M) phase of the cell cycle, the division of the mother cell into two daughter cells, each the genetic equivalent of the parent cell.

Mitosis is a continuous process by which the body grows and dead body cells are replaced, in this type of cell division each "daughter cell " contains  the exact number of chromosomes as the "parent cell" 46 also called the diploid number. The process of mitosis  in sperm is called spermatogenesis  and in the ovum , called oogenesis.\nMeiosis is a different type of cell division where reproductive cells undergo 2 sequential divisions. During meiosis the number of chromosomes is reduced to half, 23 chromosomes also called the haploid number. At the moment of fertilization (when the sperm and ovum unite) the new cell contains 23 chromosomes from the sperm and 23 chromosomes from the ova returning to the diploid number of 46 and both the mothers and fathers traits are inherited by the gamete

Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle.  \nInterphase & mitosis Interphase \n  \nThe cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division). Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible. The cell may contain a pair of centrioles (or microtubule organizing centers in plants) both of which are organizational sites for microtubules. \n \nProphase \n  \nChromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle. \n \nPrometaphase\n  \nThe nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores. Microtubules attach at the kinetochores and the chromosomes begin moving. \n \nMetaphase\n  \nSpindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.\n \nAnaphase\n  \nThe paired chromosomes separate at the kinetochores and move to opposite sides of the cell. Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules. \n \nTelophase \n  \nChromatids arrive at opposite poles of cell, and new membranes form around the daughter nuclei. The chromosomes disperse and are no longer visible under the light microscope. The spindle fibers disperse, and cytokinesis or the partitioning of the cell may also begin during this stage. \n \nCytokinesis\n \nIn animal cells, cytokinesis results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus. In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells.

No.  Meiosis is a process similar to mitosis, but the product of meiosis is four cells with half the ploidy of the parent cell.  The product of mitosis is two cells with the same ploidy as the parent cell.

>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

The replication of chromosomes does not occur during mitosis. This replication occurs during the S phase of the interphase. Think of the word SYNTHESIS when you think of the S phase. The new strands of DNA in the chromosome are SYNTHESIZED in the S phase.

S phase is the period of synthesis.  Mitosis is the nuclear division phase. If mitosis occur before DNA duplication during  anaphase or nuclear division results imbalance chromosome number. There is also some regulatory mechanism that copletion of DNA synthesis stimulates the mitosis to occur.

* Anaphase is the shortest phase of mitosis.\n    * The chromatids twins are all pulled apart at the centromere by the spindle fibers, separating as free chromosomes. Each newly separated chromosomes quickly moves to the spindle pole that its microtubule is joined.\n    * The poles of the cell get moved apart. Sister chromatds are pulled to opposite poles by shortening the microtubules joined to them.

In biology, meiosis is the process that allows one diploid cell to divide in a special way to generate haploid cells in eukaryotes. The word "meiosis" comes from the Greek meioun, meaning "to make smaller," since it results in a reduction in chromosome number.\n\nMeiosis is essential for sexual reproduction. It therefore occurs in most eukaryotes, including single-celled organisms. A few eukaryotes, notably the Bdelloid rotifers, have lost the ability to carry out meiosis and acquired the ability to reproduce by parthenogenesis. Meiosis does not occur in archaea or prokaryotes, which reproduce by asexual cell division processes.\n\nDuring meiosis, the genome of a diploid germ cell, which is composed of long segments of DNA called chromosomes, undergoes DNA replication followed by two rounds of division, resulting in haploid cells called gametes. Each gamete contains one complete set of chromosomes, or half of the genetic content of the original cell. These resultant haploid cells can fuse with other haploid cells of the opposite gender or mating type during fertilization to create a new diploid cell, or zygote. Thus, the division mechanism of meiosis is a reciprocal process to the joining of two genomes that occurs at fertilization. Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic blueprint encoded in its DNA. In other words, meiosis is the process that produces genetic variation.\n\nBiochemically, meiosis uses some of the same mechanisms employed during mitosis to accomplish the redistribution of chromosomes. There are several features unique to meiosis, most importantly the pairing and recombination between homologous chromosomes, which enable them to separate from each other.click here:http://en.wikipedia.org/wiki/Meiosis#History\n\nMitosis is the process by which a cell separates its duplicated genome into two identical halves. It is generally followed immediately by cytokinesis which divides the cytoplasm and cell membrane. This results in two identical daughter cells with a roughly equal distribution of organelles and other cellular components. Mitosis and cytokinesis together is defined as the mitotic (M) phase of the cell cycle, the division of the mother cell into two daughter cells, each the genetic equivalent of the parent cell.\n\nMitosis occurs exclusively in eukaryotic cells. In multicellular organisms, the somatic cells undergo mitosis, while germ cells — cells destined to become sperm in males or ova in females — divide by a related process called meiosis. Prokaryotic cells, which lack a nucleus, divide by a process called binary fission.\n\nBecause cytokinesis usually occurs in conjunction with mitosis, "mitosis" is often used interchangeably with "mitotic phase". However, there are many cells where mitosis and cytokinesis occur separately, forming single cells with multiple nuclei. This occurs most notably among the fungi and slime moulds, but is found in various different groups. Even in animals, cytokinesis and mitosis may occur independently, for instance during certain stages of fruit fly embryonic development.\n\nTranscription is generally believed to cease during mitosis, but epigenetic mechanisms such as bookmarking function during this stage of the cell cycle to ensure that the "memory" of which genes were active prior to entry into mitosis are transmitted to the daughter cells.click here:http://en.wikipedia.org/wiki/Mitosis#Overview

meiosis - cell divides but chromosomes are not duplicated. the product is two haploid cells with slightly different DNA (due to crossing over of chromosomes when they line up in metaphase)\nmitosis - cell divides into two identical daughter cells. if the mother cell is diploid, the two daughter cells will be too

Interphase is characterized by chromosome condensation and microtubule spindle formation and a preparatory stage for mitosis. Mitosis is characterized by the fulling away of chromosomes to opposite equatorial poles and separation. Cytokinesis and the final stage where the cytoplasm of the cell divides in two resulting in two new cells.

Mitosis result in 2 cells that are typical to the parent cell. it also occurs in all type of cells\nMeiosis result in 4 cells each of them have half of the chromosomal material of the parent cell. it occurs in gametes
104056
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!
