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. Mitosis – bone cell slides 1 2 Chromosomes copied Parent cell 3 Copies separating Cells split 4 5 2 daughter cells Plants apical meristem Rat – epithelial cells Cell membrane This powerpoint was kindly donated to www.worldofteaching.com http://www.worldofteaching.com is home to over a thousand powerpoints submitted by teachers.
