spindle fibers
spindle apparatus
Chromatids are the little strings of DNA inthe process called mitoisis
The nuclear membrane fades from view
The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
spindle fibers
spindle apparatus
58 chromatids
The chromosomes pull apart and are pulled toward opposite ends of the cell during anaphase.
During cell division the chromosomes are copied and they form sister chromatids. Then the mitotic spindle attaches to the sister chromatids and pulls them apart, splitting the nucleus in two. Then the cell goes through cytokenesis and the cell membrane is pinched together in the center, this divides the organelles and the cytoplasm between the two daughter cells.
