Understanding Mitosis: The Key to Cell Division and Growth
Mitosis is the essential process by which newly formed body cells are generated, enabling growth and the replacement of damaged or aged cells. This complex sequence involves the duplication of chromosomes and their division into two identical daughter cells, ensuring that each new cell retains the same genetic information as the parent cell. Despite sharing the same genes, different cell types specialize into various roles, such as nerve or muscle cells. Understanding mitosis is crucial for comprehending how all complex organisms develop from a single fertilized egg.

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.
