Hello Noor,

Cell division consists of three phases viz. Interphase, Mitiosis and Cytokinesis. In Interphase there is no nuclear division. Most of the cells are in interphase all the time. Next comes Mitiosis, where the division of nuclear starts and the nucleus gets divided into two smaller nuclei. And in the final phase i.e. Cytokinesis, the cytoplasm is divided into two distinct cells.

Hope this helps!
