Based on the data I have collected the stage in the cell cycle that took the longest is Interphase. As the phases of the cell cycle continues the time it takes to complete a phase decreases supporting my hypothesis. Although Interphase is the longest phase in the cell cycle, the phase that takes the least amount of time is Anaphase. Interphase is the stage in which the cell is growing up, while in Anaphase is the stage in which the chromatids are splitting into chromosomes. In the stage of Interphase, the single cell has a dot and tangled lines. Prophase is where the cell membrane starts to go away, leading us to the next stage Metaphase. Metaphase, is where the X chromosomes make a straight line in the middle of the cell. then there is Anaphase,
