Cell Division

The fission of a cell.


The division of the cytoplasm into two equal parts, usually brought about by the formation of a cell plate: mitosis; meiosis.


The way in which a cell reproduces itself.


A process by which a cell divides into two new cells. In cell division, the nucleus of the cell can divide in either of two ways — mitosis (in which identical cells are formed by division of the parent cell) or meiosis (in which the new cells have half the number of chromosomes of the original cell). Once nuclear division is complete, the cytoplasm of the cell is divided in a process called cytokinesis. Cell division is the basis of all life forms.


Reproduction of cells by division first of the chromosomes (karyokinesis) and then of the cytoplasm (cytokinesis); Cell division to produce more body (somatic) cells is by ‘mitosis; cell division during the formation of gametes is by meiosis.


The mechanisms through which cells reproduce are referred to as cell division. Mitosis is the prevailing form of cell division, resulting in the creation of daughter cells that are identical to the parent cells. On the other hand, meiosis is responsible for the production of egg and sperm cells, known as gametes, which differ from their parent cells by possessing only half the normal number of chromosomes.
