MITOSIS |
Cell division |
|
KARYOKINETIC |
Of or pertaining to karyokinesis; as, karyokinetic
changes of cell division. |
|
SCHIZO- |
A combining form denoting division or cleavage; as,
schizogenesis, reproduction by fission or cell division. |
|
VEGETABLE |
Plants without true flowers, and reproduced by minute
spores of various kinds, or by simple cell division. |
|
|
|
SEGMENT |
One of the cells or division formed by segmentation, as in
egg cleavage or in fissiparous cell formation. |
|
PROTOPHYTE |
Any unicellular plant, or plant forming only a
plasmodium, having reproduction only by fission, gemmation, or cell
division. |
|
CHROMOSOME |
One of the minute bodies into which the chromatin of
the nucleus is resolved during mitotic cell division; the idant of
Weismann. |
|
ENDOGENY |
Growth from within; multiplication of cells by endogenous
division, as in the development of one or more cells in the interior of
a parent cell. |
|
|
|
SEGMENTATION |
The act or process of dividing into segments;
specifically (Biol.), a self-division into segments as a result of
growth; cell cleavage; cell multiplication; endogenous cell formation. |
|
AMPHIASTER |
The achromatic figure, formed in mitotic cell-division,
consisting of two asters connected by a spindle-shaped bundle of
rodlike fibers diverging from each aster, and called the spindle. |
|
BASIDIUM |
A special oblong or pyriform cell, with slender branches,
which bears the spores in that division of fungi called Basidiomycetes,
of which the common mushroom is an example. |
|
CENTROSOME |
A peculiar rounded body lying near the nucleus of a
cell. It is regarded as the dynamic element by means of which the
machinery of cell division is organized. |
|
SPERMOSPHERE |
A mass or ball of cells formed by the repeated
division of a male germinal cell (spermospore), each constituent cell
(spermoblast) of which is ... |
|
KARYOSTENOSIS |
Direct cell division (in which there is first a
simple division of the nucleus, without any changes in its structure,
followed by division of t... |
|
DIASTER |
A double star; -- applied to the nucleus of a cell, when,
during cell division, the loops of the nuclear network separate into
two groups, prep... |
|
KARYOKINESIS |
The indirect division of cells in which, prior to
division of the cell protoplasm, complicated changes take place in the
nucleus, attended with... |
|
NUCLEUS |
A body, usually spheroidal, in a cell or a protozoan,
distinguished from the surrounding protoplasm by a difference in
refrangibility and in be... |
|
FISSION |
A method of asexual reproduction among the lowest
(unicellular) organisms by means of a process of self-division,
consisting of gradual divisio... |
