What is Mitosis?

Mitosis produces two daughter nuclei that have the same number of chromosomes as the parent cell and each other.

The process of Mitosis

Interphase - The cell is not dividing, chromosomes are invisible.

Prophase - The chromosomes visible and nuclear envelope disappears.

Metaphase - Chromosomes arrange at centre of cell.

Anaphase - 2 threads of a chromosomes (Chromatid) migrates to an opposite pole. Spindle fibres spilts the centromere.

Telophase - Nuclear envelope reforms.

The importance of mitosis

Growth - if new organism is to be the same to its parent, all cells that grow must posses the same set of genetic information. Mitosis ensures that this happens.

Differentiation - These different cell types each divide by mitosis to give tissues made up of identical cells which perfoms a particular function.

Repair - Mitosis replaces cells that are damaged or dead ones.
