How does the process of cellular division work?

Cellular division is the process by which a single cell divides into two or more daughter cells. There are two types of cellular division, mitosis and meiosis, which differ in the number of daughter cells produced and the genetic content of those cells.

Mitosis is the process by which a single cell divides into two identical daughter cells. It is responsible for the growth and repair of tissues in multicellular organisms. Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, the chromatin condenses into visible chromosomes, and the nuclear membrane breaks down. During metaphase, the chromosomes align along the equator of the cell. During anaphase, the sister chromatids separate and move toward opposite poles of the cell. Finally, during telophase, the chromosomes decondense, and the nuclear membrane reforms around each set of chromosomes, forming two new nuclei.

Meiosis is the process by which a single cell divides into four non-identical daughter cells. It is responsible for the production of gametes (sperm and eggs) in sexually reproducing organisms. Meiosis consists of two rounds of division: meiosis I and meiosis II. During meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing-over. This results in genetic recombination and the production of non-identical daughter cells. During meiosis II, the sister chromatids separate, resulting in four haploid daughter cells.
