There are two main types of cell division: mitosis and meiosis.
1. Mitosis: - Mitosis is a type of cell division that occurs in somatic cells (non-reproductive cells) to produce two identical daughter cells. - The main purpose of mitosis is growth, repair, and maintenance of the body. - Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. - The end result of mitosis is two diploid (2n) daughter cells, each with the same number of chromosomes as the parent cell.
2. Meiosis: - Meiosis is a type of cell division that occurs in germ cells (reproductive cells) to produce gametes (sperm and egg cells). - The main purpose of meiosis is to create genetic diversity and reduce the chromosome number by half. - Meiosis consists of two rounds of cell division: meiosis I and meiosis II, each with prophase, metaphase, anaphase, and telophase stages. - The end result of meiosis is four haploid (n) daughter cells, each with half the number of chromosomes as the parent cell.
