{Cell division} (Biol.), a method of cell increase, in which new cells are formed by the division of the parent cell. In this process, the cell nucleus undergoes peculiar differentiations and changes, as shown in the figure (see also {Karyokinesis}). At the same time the protoplasm of the cell becomes gradually constricted by a furrow transverse to the long axis of the nuclear spindle, followed, on the completion of the division of the nucleus, by a separation of the cell contents into two masses, called the daughter cells.

{Long division} (Math.), the process of division when the operations are mostly written down.

{Short division} (Math.), the process of division when the operations are mentally performed and only the results written down; -- used principally when the divisor is not greater than ten or twelve.

Syn: compartment; section; share; allotment; distribution; separation; partition; disjunction; disconnection; difference; variance; discord; disunion. [1913 Webster]
