8. The three stages of the cell cycle are -

interphase, mitosis, and cytokinesis.

Explanation:

The cell spends most of its life in interphase. In interphase, the cell goes about its normal activities. This is also the phase where it prepares for cell division by growing, duplicating its DNA, and checking for DNA damage before proceeding to mitosis. It is made up of three phases: G1, S, and G2.

Mitosis is where the cell divides its replicated genetic material into what will become two identical daughter cells. It consists of four stages, prophase, metaphase, anaphase, and telophase.

Cytokinesis is the actual process of cell division. Following the telophase stage of mitosis, the cell cytoplasm splits to form two new daughter cells, in a process called cytokinesis.
