Exploring the Phases of the Cell Cycle and Mitosis

Why is cell division important for single-cell organisms?

• It allows them to change shape.

• It helps them to move faster.

• It enables them to reproduce.

• It allows them to grow larger.

What is the role of checkpoints during the cell cycle?

• To speed up cell division.
