Mitosis is the term used for cellular division of somatic cells. Somatic cells are any body cell other than a sex cell- hair, skin, bone, etc. Somatic cells contain the diploid number of chromosomes, meaning that they contain the one set from each parent.
During mitosis, a parent cell (the original cell that undergoes cellular division) undergoes several stages - prophase, metaphase, anaphase, and telophase. During prophase, the number of chromosomes duplicates and the nucleus begins to deteriorate. During metaphase, the chromosome line up in the middle/equator of the cell. During anaphase, the chromosomes are pulled apart. Finally, during telophase, the cell begins to furrow/ split in the middle. Cytokinesis then cuts the cell into two cells. The two cells that are created from the original parent cell are called daughter cells.
