The Facts on File Dictionary of Botany
Cells produced amitotically inherit variable numbers of chromosomes. The
chances of a daughter cell lacking essential genes are less than may be
expected since many cells that characteristically divide amitotically are polyploid,
e.g. the ...
The sub-division of parent body occurs either by mitotic division or amitotically,
i.e., the body simply elongates along with the nucleus followed by a constriction
in the body, resulting in the formation of two daughter individuals. In this process
...

Surgical Pathology of Prostate & Seminal Vesicles
An amitotically dividing basal cell was ultrastructurally depicted by
Kastendieck51 (his Figure 3 1 ). The growth of hyperplastic prostate was studied
recently with an in vitro 3H-thymidine labeling method. The mitotic activity of the
epithelium ...

The macronuclei of these lower ciliates arise from micronuclei but once they have
grown in size they never themselves divide again, either mitotically or amitotically
. They do, however, show a most peculiar cycle of nucleolar activity, which is ...

The cell in development and inheritance
1 Those that divide amitotically are on the road to ruin. Amitosis in the higher
forms is thus conceived as a purely secondary process, not a survival of a
primitive process of direct division from the Protozoa, as Strasburger ('82) and
Waldeyer ...
