Mitosis is when a cell divides to create two daughter cells that are identical. Meiosis is the process by which eggs and sperm are created. In meiosis a cell divides and each daughter cell has only half the DNA.

1.synapsis occur only in meiosis. \n2.mitosis divide once, where meiosis divide twice. \n3.mitosis produce two daughter cells that are genetically identical to the parent cell, where meiosis produce four daughter cells that have only half of the chromosomes the mater cell had. \n4.meiosis have their homologous chromosomes separate!! but mitosis don't.

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.

this was an AP Biology essay question not long ago\n\nIn mitosis ther are stages of always 46 chromosomes (23 pairs)\n\nIn meiosis in different stages it varies). Once the cell divides there are 23 chrmosomes

Mitosis produces daughter cells genetically identical to the parent cell.\nThis has to be true since mitosis is the cell division producing growth - we would not expect entirely different bits and pieces to appear as we grew!\n\nThe first stage of mitosis is DNA replication. The following stages share out the exact copies of DNA equally between the daughter cells.

Any mitotic division REQUIRES cytokinesis.  It's the split of the cytoplasm and it starts in telophase, the last part of mitosis.

During the metapase of mitosis.\n\nHere's a picture that should help you out!!\nhttp://www.uhh.hawaii.edu/~ronald/392/Mitosis.JPG

It's cytokinesis.The prophase 1 of meiosis is followed by Meiosis two which is similar to mitosis.Cytokinesis is the formation of plate between the 2 daughter cells.This does not take place in prophase of any type of cell division i.e. mitosis  or meiosis.The other phenomenon is formation of bipolar spindle.This takes place in the start of metaphase.

that mitosis or meiosis occured.

the result of mitosis is 2 daughter cells which are exactly like the mother cell and that is how regular cells in the body reproduce, but in meiosis you get 4 gaughter cells that each have half the genetic material of the mother cell, in fact meiosis is like a mitosis in the begining but the cell divide once more without doubling the DNA. the cells in the reproductive glands divide like this and make the sperm and the ovuum.

Mitosis describes the process by which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA\nMeiosis, is the process by which certain sex cells are created. If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg 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.

Phases of mitosis\n \nThe cell cycle.The mitotic phase is a relatively short action-packed period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for division. Interphase is divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). During all three phases, the cell grows by producing proteins and cytoplasmic organelles. However, chromosomes are replicated only during the S phase. Thus, a cell grows (G1), continues to grow as it duplicates its chromosomes (S), grows more and prepares for mitosis (G2), and divides (M).\n\nMitosis is a continual and dynamic process. For purposes of description, however, mitosis is conventionally broken down into five subphases: prophase, prometaphase, metaphase, anaphase, and telophase.\n\n[edit]\nProphase\n \nProphase: The two round objects above the nucleus are the centrosomes. Note the condensed chromatin.Main article: Prophase \nNormally, the genetic material in the nucleus is in a loosely bundled coil called chromatin. At the onset of prophase, chromatin condenses together into a highly ordered structure called a chromosome. Since the genetic material has already been duplicated earlier in S phase, the chromosomes have two sister chromatids, bound together at the centromere by the protein cohesin. Chromosomes are visible at high magnification through a light microscope.\n\nJust outside the nucleus are two centrosomes. Each centrosome, which was replicated earlier independent of mitosis, acts as a coordinating center for the cell's microtubules. The two centrosomes sprout microtubules (which may be thought of as cellular ropes or poles) by polymerizing free-floating tubulin protein. By repulsive interaction of these microtubules with each other, the centrosomes push themselves to opposite ends of the cell (although new research has shown that there might be a mechanism inside the centromeres that also grab the microtubules and pull the chromatids apart). The network of microtubules is the beginning of the mitotic spindle.\n\nSome centrosomes contain a pair of centrioles that may help organize microtubule assembly, but they are not essential to formation of the mitotic spindle. Plant cells that lack centrioles have no trouble undergoing mitosis.\n\n[edit]\nPrometaphase\n \nPrometaphase: The nuclear membrane has degraded, and microtubules have invaded the nuclear space. These microtubules can attach to kinetochores or they can interact with opposing microtubules.Main article: Prometaphase \nThe nuclear envelope dissolves and microtubules invade the nuclear space. This is called open mitosis, and it occurs in most multicellular organisms. Some protists, such as algae, undergo a variation called closed mitosis where the microtubules are able to penetrate an intact nuclear envelope.\n\nEach chromosome forms two kinetochores at the centromere, one attached at each chromatid. A kinetochore is a complex protein structure that is analogous to a ring for the microtubule hook; it is the point where microtubules attach themselves to the chromosome. Although the kinetochore is not fully understood, it is known that it contains a molecular motor. When a microtubule connects with the kinetochore, the motor activates, using energy from ATP to "crawl" up the tube toward the originating centrosome. The kinetochore provides the pulling force necessary to later separate the chromosome's two chromatids.\n\nWhen the spindle grows to sufficient length, kinetochore microtubules begin searching for kinetochores to attach to. A number of nonkinetochore microtubules find and interact with corresponding nonkinetochore microtubules from the opposite centrosome to form the mitotic spindle.CXV\n\nPrometaphase is sometimes considered part of prophase.\n\n[edit]\nMetaphase\n \nMetaphase: The chromosomes have aligned at the metaphase plate.Main article: Metaphase \nAs microtubules find and attach to kinetochores in prometaphase, the centro

Mitosis is the splitting of one cell into two daughter cells.  The phases can be summed up into the acronym IPMAT.\n\nI interphase - has a G1 or growth one phase where cellular growth and DNA translation occur.  S or Synthesis phase where DNA is translated assembled and condensed.  G2 or growth two phase where cytoplasmic growth occurs.\n\nP prophase - where DNA starts condensing into chromosomes and centromeres polarise the cell forming spindal fibers.\n\nM metaphase - is when DNA is fully condenced and chromosomes are in equatorial allignment\n\nA anaphase - karyokenesis is complete, new nuclear membranes form and cytokenesis begins furrowing.\n\nT telephase - clevage furrowing completes to initiate a new G1 phase.
