  1. Mitosis Cell division Visit www.worldofteaching.com For 100’s of free powerpoints

  2. Cell division All complex organisms originated from a single fertilised egg. Every cell in your body started here, through cell division the numbers are increased Cell then specialise and change into their various roles

  3. Mitosis • Mitosis is the process by which new body cell are produced for: • Growth • Replacing damaged or old cells. This is a complex process requiring different stages

  4. Parent cell Chromosomes are copied and double in number Chromosomes now split 2 daughter cells identical to original

  5. Mitosis • All daughter cells contain the same genetic information from the original parent cell from which it was copied. • Every different type cell in your body contains the same genes, but only some act to make the cells specialise – e.g. into nerve or muscle tissue.
