Mitosis Cell division

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

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

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.
