Cell cleavage is multiplication of cells by fission. \n\nMitosis is the process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes. It is also called karyokinesis. :)

The beginning of somatic cell division or mitosis is called prophase. In early prophase, the centrosomes move toward opposite poles of the cell, organizing the spindle microtubules between them. The sister chromatids become visible in the nucleus as they condense.In late prophase, the nuclear membrane breaks down and some of the spindle microtubules attach to the sister chromatids. The microtubules pull the chromatid pairs to the midline of the cell, or metaphase plate.The chromatids remain lined up between the poles of the cell during metaphase.Anaphase begins when the pairs of sister chromatids separate. The separated chromatids are now called chromosomes, and move toward the poles of the cell.The chromosomes arrive at the poles in telophase, and new nuclear membranes form around them.Division of the cytoplasmic components is called cytokinesis.In animal cells, cytokinesis occurs when a ring of actin and myosin filaments constricts the plasma membrane at the equator. Eventually, the parent cell is divided into two cells.Meiosis I-Prophase I-In the leptotene stage, the cell's genetic material, which is normally in a loosely arranged pile known as chromatin, condenses into visible threadlike structures. Along the thread, centromeres are visible as small beads of tightly coiled chromatin. Recall that centromeres are connection sites between sister chromatids, which are not yet distinguishable. As the chromatin becomes progressively ordered and visible, homologous chromosomes find each other and bind together. In this process, called synapsis, a protein structure called the synaptonemal complex attaches the homologous chromosomes tightly together all along their lengths.The zygotene stage sees the completion of synapsis. The paired homologous chromosomes are said to be bivalent. They may also be referred to as a tetrad, a reference to the four sister chromatids. During this stage, one percent of DNA that wasn't replicated during S phase is replicated. The significance of this cleanup act is unclear.The pachytene stage heralds crossing over. Nonsister chromatids of homologous chromosomes exchange segments of genetic information. Because the chromosomes cannot be distinguished in the synaptonemal complex, the actual act of crossing over is not perceivable through the microscope.During the diplotene stage, the synaptonemal complex degrades. Homologous chromosomes fall apart and begin to repel each other. The chromosomes themselves uncoil a bit, allowing some transcription of DNA. They are held together by virtue of recombination nodules, betraying the sites of previous crossing over, the chiasmata.Chromosomes recondense during the diakinesis stage. Sites of crossing over entangle together, effectively overlapping, making chiasmata clearly visible. In general, every chromosome will have crossed over at least once. The nucleoli disappears and the nuclear membrane disintegrates into vesicles.During these stages, centrioles are migrating to the two poles of the cell. These centrioles, which were duplicated during interphase, function as microtubule coordinating centers. Centrioles sprout microtubules, essentially cellular ropes and poles, during crossing over. They invade the nuclear membrane after it disintegrates, attaching to the chromosomes at the kinetochore. The kinetochore functions as a motor, pulling the chromosome along the attached microtubule toward the originating centriole, like a train on a track. There are two kinetochores on each tetrad, one for each centrosome. Prophase I is the longest phase in meiosis.Microtubules that attach to the kinetochores are known as kinetochore microtubules. Other microtubules will interact with microtubules from the opposite centriole. These are called nonkinetochore microtubules.Metaphase I-As kinetochore microtubules from both centrioles attach to their respective kinetochores, the homologous chromosomes align equidistant above and below an imaginary equatorial plane, due to cont

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.

Here's what they have in common:\n1. Cell membrane is present.\n2. Vacuoles are present.\n3. Both are living cells.\n4. Mitochondria is present.\n5. Both are eukaryotic cells. \n6. Nucleus, nuclear membrane and chromatin fibers are present.\n7. Both can reproduce through mitosis. (Advanced animal cells reproduce through meiosis)\n\nPS : Don't take note of those who talk of the absence of mitochondria in plants. It's present. Only chloroplast is absent in animal cell.

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.

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.

Both involve prophase, metaphase, anaphase and telophase. Both involve cytokinesis, and lastly DNA is replicated just before cells enter either mitosis or meiosis.

When a cell divides you get a new cell. There are actually four main stages of cell division. They are:\nProphase\nMetaphase\nAnaphase\nTelophase.\n\nIf you want more information, I would suggest trying Wikipedia, or your local library.

Both are eukaryotic (containing a "true nucleus").  \n\nAnimal Cells lack a cell wall and adjacent cells are connected by junctions (adhesive, gap or tight).  Animal cells contain centrioles (help create microtubules used in mitosis and meiosis) and lysosomes (organelles used to digest wastes and old organelles). During telophase and cytokinesis the cells separate via a cleavage furrow.\n\nPlant Cells contain a cell wall (think of the cell wall as the "skeleton" composed mainly of cellulose) and rely on turgor pressure to keep them upright.  Adjacent cells are connected by channels called plasmodesmata.  You will not find centrioles or lysosomes in a plant cell, but you will find a really cool organelle called a large centrol vacuole.  This organelle is where the water is stored in a cell and it helps maintain the turgor pressure described above.  It also acts as a lysosome, storing chemicals and waste products.  The Central vacuole can also store the pigments you see in flowers as well as poisons used to deter predators.  And of course, in a plant cell you will find the plasts as mentioned by someone earlier.. including the famous chloroplasts (the site for photosynthesis) as well as the chromoplasts (contain pigments) and amyloplasts (specialized for starch storage). During telophase and cytokinesis, the cells are separated by a structure called a cell plate.   \n\nUmmm, that's all I can come up with right now!

In very simple terms:\n\nmitosis is the division of somatic cells, one cell divides and the end result is 2 cells.   \n\nmeiosis is the division of germ cells, one cell divides into two first and those two divide again, and the end result is 4 cells.

Plant cells differentiate in many tissues, like leaf, xilem, phloem, root and many others. It's the same for us, an animal cell can differentiate into a liver cell, a brain cell, a skin cell....\nPlants, unlike us, have regions of undifferentiated cells, called meristems. The main meristem of the shoot is at the top, called the terminal bud. Theese cells divide and produce the elongation of the shoot, and as they become more and older they produce new shoot, leafs and stuff.\nOther meristems, axial buds, are kept right in the place where the leaf meets the shoot. When this buds start growing in the same way the terminal buds do, branches arise.\nOther regions of meristematic tissue are right between the phloem (where the sap flows) and the xilem (where the water flows) all along the shoot. This region is called the Vascular Cambium.\n\nNormally, the terminal bud secretes hormones to the sap that keep the other meristematic tissues at rest. This is to avoid a lot of branches beeing produced before the roots can cope with the water demand of a lot of leafs.\nWhen you cut the shoot, the terminal bud dissapears, so the axial buds and even the cambium start dividing and differentiating into new shoots. \nThe reason why this new growth happens near the cut is because this would be the youngest axial buds and cambium, and therefore the most active ones (or the ones that can more readily be activated).

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 occurs in animals too guys.

the above answers are all correct\nCytokinesis is an eventual outcome of mitosis\nwhen mitosis or cell division happens when all the DNA and proteins are already prepared the cytoplasm divides (cytokinesis) leading to 2 new cells and cytokinesis happens in certain phases of mitosis like anaphase and telophase

The biggest difference is the cellulose wall that is present on all plant cells but not on animal cells.
