The document summarizes the stages of mitosis and cell division. It describes the key events in each phase of mitosis including nuclear division and cytokinesis. Specifically, it explains that during interphase the cell grows and duplicates its DNA in preparation for division. During mitosis, the duplicated chromosomes align and separate into two identical sets pulled to opposite sides of the cell by spinning fibers. Finally, cytokinesis divides the cytoplasm through formation of a cell plate in plant cells or cleavage furrow in animal cells, forming two daughter cells each with the same number and type of chromosomes as the original parent cell.
