The illustration shows the cell cycle of a eukaryotic plant or animal cell. This cycle begins when the cell is produced by mitosis and runs until the cell undergoes its own mitosis and splits in two. The cycle is divided into distinct phases: G1 (gap 1) S (synthesis), G2 (gap 2), and M (mitosis). As you can see, mitosis only occupies a fraction of the cycle.
