cell division is complicated if you're doing mitosis or miosis, but i'll try to explain. During mitosis, the cell prepares to split in interphase by making copies or the DNA and organelles needed for two cells rather than one. The cell goes through metaphase, anaphase, and telephase which basically just prepares the cells to be separated and cytokinesis is the splitting of the cell membrane all together, making the cells two seperate ones.
