Importance of Mitosis

Importance

  • All cells in the body (excluding gametes) are produced by mitosis of the zygote

Occurs in

  • Growth: mitosis produces new cells
  • Repair: to replace damaged or dead cells
  • Asexual reproduction: mitosis produces offspring that are genetically identical to the parent
