The document discusses cell division and the cell cycle. It defines cell division as the process where one cell divides into two or more daughter cells. The cell cycle consists of interphase and mitosis. Interphase includes gap 1 (G1), DNA synthesis (S), and gap 2 (G2) phases. Mitosis has prophase, metaphase, anaphase and telophase stages where the chromosomes separate and two daughter cells form. The stages of mitosis and their key events are described in detail. Different cell types divide at different rates depending on body needs.
