Unformatted text preview: Why are mitosis and meiosis both important to a living organism? When would an organism need to undergo each process of mitosis and meiosis? What would happen if meiosis did not occur? Mitosis: Organisms have a certain number of chromosomes in their cells. Before a cell divides into two cells, it must make copies of all its chromosomes. After the cell makes copies of its chromosomes, it goes through the process of mitosis. Mitosis is the process by which a cell duplicates its chromosomes and divides them between two new cells in one division. The new cells produced by this division have the exactly same chromosomes as the parent cell. This division keeps the chromosome number equal also thus every human body cell has 46 chromosomes. There are five stages of mitosis each with their own functions and characteristics. Mitosis and meiosis are similar processes in that they both result in the separation of existing cells into new ones. They differ, however, in their specific processes as well as in their products. The reason for these differences lies in the difference in the class of cells that each process creates. Mitosis is the process in which a parent cell splits into two daughter cells that are exactly alike.in which a parent cell splits into two daughter cells that are exactly alike....
