What do cells need to do between divisions to make sure that they dont just get smaller and smaller?

Cytokinesis is less complex than mitosis because it is simply the splitting of the cytoplasm to produce two daughter cells or two new cell membranes. It only follows the sequential phases that mitosis have. Mitosis is a continuous process which has four sequential phases namely, prophase, metaphase, anaphase, and telophase. Mitosis is the complete splitting of the cell involving much more processes than cytokinesis including the interphase and DNA replication.
