Am`i*to"sis, n. [NL. See A-not, and Mitosis.] (Biol.)
Definition: Cell division in which there is first a simple cleavage of the
nucleus without change in its structure (such as the formation of
chromosomes), followed by the division of the cytoplasm; direct cell
division; -- opposed to mitosis. It is not the usual mode of
division, and is believed by many to occur chiefly in highly
specialized cells which are incapable of long-continued
multiplication, in transitory structures, and in those in early
stages of degeneration.
