How are mitosis and meiosis different? Why is mitosis important to organisms? mitosis, a process ofcellduplication, orreproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the termmitosisis used to describe the duplication and distribution ofchro...
