mitosis
(gcide) | Karyokinesis \Kar"y*o*ki*ne`sis\
(k[a^]r`[i^]*[-o]*k[-i]*n[=e]"s[i^]s), n. [NL., fr. Gr.
ka`ryon a nut, kernel + kinei^n to move.]
1. (Biol.) The indirect division of cells in which, prior to
division of the cell protoplasm, complicated changes take
place in the nucleus, attended with movement of the
nuclear fibrils; -- opposed to karyostenosis. The
nucleus becomes enlarged and convoluted, and finally the
threads are separated into two groups which ultimately
become disconnected and constitute the daughter nuclei.
Called also mitosis. See Cell development, under
Cell.
[1913 Webster]
2. The changes that occur in the nucleus of a cell,
especially movements of the chromosomes, in the process of
cell division.

Amitosis
(gcide) | Amitosis \Am`i*to"sis\, n. [NL. See A- not, and Mitosis.]
(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.
