1. Mitosis
Cell division

2. Cell division
All complex organisms originated from a single fertilized egg.
Every cell in your body began here, then through cell division the numbers are increased.
Cells then specialize 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.
