Explanation:

G1 is the first stage of the cell cycle, and it is essential for cell growth.

G2 is the next phase, and it involves preparing and growing the cell for mitosis.

Mitosis is the next stage, where the cell divides into 2.

Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.
