differences between plant and animal mitosis?

plant cells form a disk during the final splitting phase, while animal membranes constrict.  Also, it is easier to see earlier in animals, and animals have centrioles, plants dont.  thats all my textbook says.  the phases and everything are the same, though.

You could do a project on the processes of Meiosis and/or Mitosis and how they are similar and different. Meiosis is the splitting of cells for the growth of an organism, and Mitosis is the splitting of a cell into 4 gametes for reproduction of an organism. It's a pretty interesting project.

Mitosis, also called karyokinesis, is division of the nucleus and its chromosomes.  It is followed by division of the cytoplasm known as cytokinesis.  Both mitosis and cytokinesis are parts of the life of a cell called the Cell Cycle.  Most of the life of a cell is spent in a non-dividing phase called Interphase.  Interphase includes G1 stage in which the newly divided cells grow in size, S stage in which the number of chromosomes is doubled and appear as chromatin, and G2 stage where the cell makes the enzymes & other cellular materials needed for mitosis.\n\nMitosis has 4 major stages --- Prophase, Metaphase, Anaphase, and Telophase. When a living organism needs new cells to repair damage, grow, or just maintain its condition, cells undergo mitosis.\n\nDuring Prophase, the DNA and proteins start to condense. The two centrioles move toward the opposite end of the cell in animals or microtubules are assembled in plants to form a spindle. The nuclear envelope and nucleolus also start to break up.\n\n\nProphase\n\nDuring Metaphase, the spindle apparatus attaches to sister chromatids of each chromosome. All the chromosomes are line up at the equator of the spindle. They are now in their most tightly condensed form.\n\n\nMetaphase\n\nDuring Anaphase, the spindle fibers attached to the two sister chromatids of each chromosome contract and separate chromosomes which move to opposite poles of the cell.\n\n\nAnaphase\nIn Telophase, as the 2 new cells pinch in half (animal cells) or a cell plate forms (plant cells), the chromosomes become less condensed again and reappear as chromatin. New membrane forms nuclear envelopes and the nucleolus is reformed.

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.

During prophase. But it actually doesn't happen in all organisms. Yeast for example has a nuclear duplication and division without ever breaking down the nuclear membrane.

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.

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.

plant cells have vacuoles and chloroplasts while animal cells dont. plant cells synthesize their own foods while animal cells dont.\n\nribosomes are the organelles that synthesize proteins using RNA from the nucleus.\n\nI just cant seem to remember what the answer of the third question was.

Animal and plant cells share the same basic structures with a few exceptions.  First of all, plant cells are surrounded by a cell wall made of chitin that is extremely important in regulating water levels.  Animals cells have no cell walls.  Plant cells use chloroplast to create their energy, rather than the mitochondria that humans use.  In plant cells, the storage form of glucose is starch, whereas in animal cells it is glucagon.  There are many more small differences, but these three are big ones.

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.

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...

Cytokinesis is the process whereby the cytoplasm of a single cell is divided to spawn two daughter cells. It usually initiates during the late stages of mitosis, splitting a binucleate cell in two to ensure that chromosome number is maintained from one generation to the next. One notable exception to the normal process of cytokinesis is oogenesis (the creation of an ovum in the ovarian follicle of the ovary), where the ovum takes almost all the cytoplasm and organelles, leaving very little for the resulting polar bodies, which then die. In plant cells, a dividing structure known as the cell plate forms across the centre of the cytoplasm and a new cell wall forms between the two daughter cells.\nThe big difference between animal and plant cell cytokinesis is that the animal cell develops a cleavage furrow that essentially pinches through the middle of the two new cells that will form two separate new cells.  In plant cells there is a new cell wall that begins to form between the two new forming cells called the cell plate.  This cell plate begins at the center of the two new cells and continues to grow outward towards the existing cell wall, finally dividing the one cell into two.

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 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 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.

THERE ARE FOUR DIFFERENCES!!!!!!! NOT THREE. Some people say five\n\n1) Chloroplasts\n2) Central Vacuole and tonoplast (the membrane enclosing the vacuole)\n3) Cell Wall\n4) Plasmodesmata (channels through cells walls that connect cytoplasms of adjac3ent cells.)

If we were talking about human cells, there are 23 chromosomes in each cell. In mitosis, there are four main steps with another peparation time. The four are Prophase, Metaphase, Anaphase, and Telephase (PMAT). The peparation time before mitosis is called Interphase (not a step of mitosis) where chromosomes duplicate themselves (23 x 2 = 46 chromosomes total). During these steps of mitosis, the cell divides into two. So if a cell with 46 chromosomes divide into two daughter cells, then each daughter cell will have 23 chromosomes in the end. The result of mitosis: more cells with the same number of chromosomes in each cell.\n\nA cell goes through a cell cycle.
