Flexi Says: Cell division is part of a cycle of cellular growth and division known as the cell cycle—cells must grow before they divide. The cell cycle describes the "life" of a eukaryotic cell. In addition to cell division, the cell cycle includes the division of the nucleus and the cytoplasm. Most cell division produces genetically identical cells, meaning they have the same DNA. The process of mitosis, which specifically is the division of the nucleus, ensures that each cell has the same DNA. During mitosis, the chromosomes equally separate, thus making sure each nucleus in each resulting cell after cell division is genetically identical. A special form of cell division, called meiosis, produces cells with half as much DNA as the parent cell. These cells are used for reproduction.
