Understand that mitosis is the process of cell division that results in two genetically identical daughter cells, primarily for growth, repair, and maintenance in multicellular organisms.
Identify the types of cells in humans: somatic cells (all body cells except reproductive cells) and germ cells (which undergo meiosis to form gametes).
Recognize that mature red blood cells (erythrocytes) lack nuclei and do not undergo mitosis, so they are excluded.
Recall that prokaryotic cells do not undergo mitosis; instead, they divide by binary fission, a different process.
Conclude that mitosis primarily occurs in somatic (non-reproductive) cells, which are responsible for tissue growth and repair.
