Pertaining to amitosis or occurring through amitosis; relating to direct cell division, characterized by the simple cleavage of the nucleus and cytoplasm without the individualization of chromosomes and without the formation of the mitotic apparatus (spindle). This physiological structural mechanism is specific to certain specialized, aged, pathological cells or lower unicellular organisms.
