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

After telophase II of meiosis, each of the four daughter cells has exactly half the number chromosomes that are present in the parental cell. Unless more is known about the genetical make of the parental cell one can’t make any statement about their genetic make up.

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.

remember the phases in meiosis (in order) :Prophase, Metaphase, anaphase, telephase (pmat)\nMitosis\nI  INTRODUCTION \n\nMitosis, process in which a cell’s nucleus replicates and divides in preparation for division of the cell. Mitosis results in two cells that are genetically identical, a necessary condition for the normal functioning of virtually all cells. Mitosis is vital for growth; for repair and replacement of damaged or worn out cells; and for asexual reproduction, or reproduction without eggs and sperm.\n\nAll multicellular animals, plants, fungi, and protists, which begin life as single cells, carry out mitosis to develop into complex organisms containing billions of cells. Mitosis continues in full-grown organisms as a means of maintaining the organism—replacing dying skin cells, for example, or repairing damaged muscle cells. In the cells of the adult human body, mitosis occurs about 25 million times per second. Multicellular organisms such as sea stars, sea anemones, fungi, and certain plants rely on mitosis for asexual reproduction at particular stages in their life cycles, and mitosis is the sole mode of reproduction for many single-celled organisms.\n\nII  INTERPHASE \n\nThe life cycle of eukaryotic cells, or cells containing a nucleus, is a continuous process typically divided into three phases for ease of understanding: interphase, mitosis, and cytokinesis. Interphase includes three stages, referred to as G1, S and G2. In G1, a newly formed cell synthesizes materials needed for cell growth. In the S stage, deoxyribonucleic acid (DNA), the genetic material of the cell, is replicated. At this stage, DNA consists of long, thin strands called chromatin. As each strand is replicated, it is linked to its duplicate by a structure known as a centromere. When the S stage is complete, the cell enters a brief stage known as G2, when specialized enzymes correct any errors in the newly synthesized DNA, and proteins involved with the next phase, mitosis, are synthesized. \n\nIII  MITOSIS \n\nMitosis occurs in four steps. In prophase the replicated, linked DNA strands slowly wrap around proteins that in turn coil and condense into two short, thick, rodlike structures called chromatids, attached by the centromere. Two structures called centrioles, both located on one side of the nucleus, separate and move toward opposite poles of the cell. As the centrioles move apart, they begin to radiate thin, hollow, proteins called microtubules. The microtubules arrange themselves in the shape of a football, or spindle, that spans the cell, with the widest part at the center of the cell and the narrower ends at opposite poles. As the spindle forms, the nuclear membrane breaks down into tiny sacs or vesicles that are dispersed in the cytoplasm. Final disintegration of the membrane marks the beginning of metaphase. \n\nIn metaphase, the spindle fibers attach to the chromatids near the centromeres, and tug and push the chromatids so that they line up in the equatorial plane of the cell halfway between the poles. Like two individuals standing back to back at the equator, one chromatid faces one pole of the cell, and its linked partner faces the opposite pole. This precise orientation is necessary in order for the next step, anaphase, to occur. Anaphase begins when the centromeres split, separating the identical chromatids into single chromosomes, which then move along the spindle fibers to opposite poles of the cell. \n\nAs these two identical groups of single chromosomes gather at opposite poles of the cell, telophase begins. A new nuclear membrane forms around each new group of chromosomes. The spindle fibers break down and the newly formed chromosomes begin to unwind. If viewed under a light microscope, the chromosomes appear to fade away. They exist, however, in the form of chromatin, the extended, thin strands of DNA too fine to be seen except with electron microscopes. Mitosis accomplishes replication and division of the nucleus,

the daughter cell will not have the correct amount of chromosomes if S phase does not occur. \n\nthe daughter cell will not have the same amount of chromosomes as parent cell for mitosis, \n\nand daughter cell will not have half the number of chromosomes as parent cell for meiosis.

During mitosis one of our cells (such as a skin cell for instance) divides to form two cells each of which is identical to the single parent cell, each new cell has the same ploidy, if the originating cell is diploid then the two progeny cells are diploid and identical to the parent cell. Mitosis is the kind of cell division that occurs when body cells replace each other during normal aging and wear and tear bodily growth, in cells such as those of the skin, digestive tract etc. Since this kind of cell division is non sexual it is also often described as vegetative division, and since it produces exact copies of the parent cell it is sometimes called clonal division. The function, then, of mitosis, is to ensure that each of the two new cells generated from one receives one of the sister chromatids from each chromosome in the original cell.

Penguin says >>\n\nOogenesis is the process of females creating egg cells... When women are born, they have a lot of cells that of those egg cells, only a few will undergo meiosis and form egg cells. Meiosis, yes, does form four haploid cells from each one of those "pre-made egg cells". All those four haploid cells has 23 chromosomes. However, Meiosis only ensures that there are enough chromosomes for the offspring, and not necessarily the quality of the egg cell... \n\nWhat I mean is >> The larger egg cell containing more cytoplasm lives, while the other doesn't develope into an ovum. \n\nIn Meiosis I, the original cell divides into two, with 46 chromosomes. Meiosis does not seperate into two equal cells, as they do in mitosis. The larger cell then splits again [Meiosis II], and of the two haploid cells that result from Meiosis II, the larger one lives again. So, only one gamete is formed, though of the 4 haploids, 3 of the haploids degenerate. \n\n-- Cytokinesis isn't part of mitosis...Mitosis is part of the cell cycle, which has 3 steps :: interphase, mitosis, and cytokinesis. \n\nRemember that mitosis is the process of splitting a cell's nucleus. \n\nand remember that cytokinesis only splits two cells in half by pinching the cell membrane...\n\nSo... there's a difference. \n\nThank -you-\n\n<< Penguin waves good bye.

Mitosis is the process of cell division.  Our cells are constantly dying off.  Mitosis allows living organisms to continue to survive by replacing the dying cells.

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.

B. Secondary spermatocytes... spermatids are the product of the meiosis II which under go metamorphosis to become spermatozoa, but they don't go through meiosis again
