These 10 animal facts will amaze you. The cell cycle is a process in which a cell grows and divides to create a copy of itself. Some organisms reproduce exclusively through this process, while in complex multicellular life, it allows an organism to grow, and to replace cells as they become worn out.
Introducing the Cell Cycle. The eukaryotic cell cycle is divided into four phases, designated G 1, S, G 2, and M respectively (see the figure to the right). Collectively, the G 1, S, and G 2 phases are referred to as interphase (designated I in the figure), and take up approximately 90% of the cell's lifespan.ntroducing the Cell Cycle.
