New cells are formed by the process of mitosis, a type of cell division that produces cells that are genetic replicas of the original cell. Not all cells in an organism undergo mitosis at the same rate. There are five stages in the cell cycle: interphase, prophase, metaphase, anaphase, and telophase. The duration of each stage varies among organisms of plants and animals; hence we observed the cell cycle of the Broad bean ( Vicia faba ), Onion ( Allium cepa ), and Whitefish ( Coregonus clupeaformis ). For all three organisms the greatest number of cells were undergoing interphase and second were in prophase for both group and class data.
