Cut out the cell diagrams and tape/glue them across the top under the appropriate phase label.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. 7/22/2009 Cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes.
