Mitosis and Asexual Reproduction

1)     Growth and repair of tissue
2)     Occurs in ALL organisms

Asexual reproduction – involves only ONE parent. The offspring have identical genes to the parent – so there’s no variation between parent and offspring

Mitosis – when a cell reproduces itself by splitting to form two cells with identical sets of chromosomes

1)      When the cell gets the signal to divide, the chromosomes duplicate. It forms X-shaped chromosomes and each “arm” is an exact duplicate of the other.

2)     The chromosomes line up in the middle of the cell and cell fibres pull them apart. The two arms of each chromosome go to separate sides of the cell

3)     Membranes form around each of the sets of chromosomes.
