( ) The cell rounds up.
( ) The endoplasmic reticulum collapses.
( ) The Golgi apparatus fragments.
( ) The primary cilium is resorbed (disappears).
( ) The contractile ring forms and constricts.

The change in the organization of the actin-based cell cortex leads to round cells that are later cleaved into two daughter cells by the actin-based contractile ring. The network of endoplasmic reticulum membranes and Golgi stacks lose their interphase distribution during mitosis as a result of a profound reorganization of the microtubules, which also affects the microtubule-based primary cilia.
