Mitosis and Meosis Quiz

Mitosis is the scientific term for nuclear cell division, where the nucleus of the cell divides, resulting in two sets of identical chromosomes. Mitosis is accompanied by cytokinesis in which the end result is two completely separate cells called daughter cells.

Division of cells in which four "daughter" cells are produced from one "parent" cell, each with half the genes of the parent. Meiosis is a special kind of cell division that produces haploid (1n) cells. a type of cell division in which parent cell divide to two daughter offspring with half number of chromosomes in each new cell.

Both Mitosis and Meiosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus: After Mitosis, each of the daughter cells will have exactly the same DNA strands, while after Meiosis each daughter cell will only have half of the DNA strands. (Sometimes the division is not exactly half/half, but that is not important for this answer) Because Meiosis only has half the information that the parent cell had, the cell is (as far as we know) unable to reproduce by itself. The reason for Meiosis is for reproduction of a multi-cellular organism. One daughter cell (from the male of the species) will try to find a compatible daughter cell (from the female of the species) and fertilize it. This then becomes and embryo and the specie has successfully reproduced. And this is how you, the reader, came into existence
