namitosisthe direct method of cell division characterized by simple division of the nucleus without formation of chromosomes
Webster's Revised Unabridged Dictionary
nAmitosis(Biol) 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.
Century Dictionary and Cyclopedia
namitosisIn cytology, direct celldivision, akinesis or karyostenosis, as opposed to the indirect form of division (mitosis, karyokinesis, which see): so called from the absence of thread-like figures in the nucleus.
