The primary purpose of cell division in multicellular organisms is to facilitate growth, repair, and reproduction. During development, cell division allows organisms to increase in size and replace damaged or dead cells. The processes of mitosis and meiosis are essential forms of cell division. Mitosis results in two genetically identical daughter cells, while meiosis leads to the production of gametes (sperm and eggs) with half the genetic material, facilitating sexual reproduction. Overall, cell division is vital for maintaining homeostasis and ensuring the proper function of organisms.
