• mitosis


  when a cell produces a genetically identical copy of itself called a daughter cell
• Reasons for mitosis


  te replace damaged cells

  to produce new cells for growth

• Steps in Mitosis


  1. chromosomes are copied during the interface
  2. chromosomes line up on the equator
  3. chromosomes are pulled to opposite ends/poles of the cell
  4. chromosomes separate and cell divides in two
  5. two genetically identical daughter cells have been produced
