The . cell cycle. is a repeated pattern of growth and division that occurs in eukaryotic cells. . This cycle consists of three phases: G1, S, G2. The first phase represents cell growth while the last two phases represent cell division.. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells.
