The nucleus assumes a characteristic spindle shape and subsequently divides.

The nucleus of the parent cell divides several times by mitosis, producing several nuclei.

The nucleus and the chromosomes divide, and the mitochondria divide also.

It will later reform when the nucleus divides completely.

The nucleus of oocyst divides repeatedly to form large number of daughter nuclei.

This region is the particular part of a chromosome that is associated with a nucleolus after the nucleus divides.

The two nuclei then divide to form four nuclei, similar to fungi with four-spored basidia (12, 13).

In this stage, the nucleus divides multiple times with a concomitant increase in cell size but without cell segmentation.

During binary fission in amoeba, the nucleus divides amitotically into two, which is followed by the division of cytoplasm.

During asexual reproduction, the nucleus divides yielding two daughter cells one of which exits through the opening in the lorica.
