When mitosis is about to take place, they separate from one another and pass to the poles of the nucleus, forming the achromatic spindle.
This is imperative if cell mitosis is to continue, as cell division will only occur if cells are kept at body temperature.
It has been shown that, in cells of Spiro gyra placed under special conditions, amitotic division can be induced, and that normal mitosis is resumed when they are placed again under normal conditions.
More so they undergo mitosis at similar rates when compared to control samples.
Here the cell is about to start entering mitosis.
