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

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

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

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.
