Brain cells, heart muscles Is resting phase where cells continue to carry out normal cellular process, but do not need to grow and divide If cells need to start dividing again, it is possible for them to re-enter the cell cycle at the G1 phase. Eventually 17 demands Cell show himself only for Cell to appear behind and absorb him causing the mission to be a success, though Elder Kai notes that Cell’s success doesn't make it a happy ending though Chronoa states that its a part of the original history so they can't change it and things do eventually work themselves out in the end. This process is cyclical because every cell forms from a preexisting cell. The cell has to undergo division for the growth and to maintain genetic continuity.
