Pseudoamitosis

Pseudoamitosis (pseudo- + amitosis) is a type of cell division in which the nucleus divides without forming a spindle and does not go through the mitosis stage. Instead, the core is directly laced into two parts. This process occurs in some protists and fungi.

With pseudoamitosis, the nuclear membrane begins to bulge inward in one or more places. Then constrictions are formed, which deepen until the core is divided into two parts. The chromosomes remain in a spiral state and are randomly distributed between the daughter nuclei.

This method of nuclear division, unlike mitosis, does not ensure equal distribution of genetic material between daughter cells. Therefore, pseudoamitosis is considered a primitive method of division, characteristic of low-organized unicellular eukaryotes.
