Slide 1

Mitosis

Cell division

Slide 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

Slide 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

Slide 4

2 daughter cells identical to original

Parent cell

Chromosomes are copied and double in number

Chromosomes now split

Slide 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.
