Match the stage of the Cell Cycle to its description.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Mitosis "M" Phase | arrow_right_alt | The cell grows for the first time and duplicates (copies) its organelles. |
G2 Phase | arrow_right_alt | The cell duplicates (copies) its DNA. |
G1 Phase | arrow_right_alt | The cell grows for a second time and goes through the checkpoint. |
Synthesis "S" Phase | arrow_right_alt | The nucleus divides to form two identical healthy daughter cells. |
Label the diagram of the cell cycle.

The purpose of the cell cycle is . If the cell passes the G2 checkpoint, the cell completes mitosis and produces .
Match each of the 4 steps of mitosis to its definition.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Metaphase | arrow_right_alt | The step of Mitosis when the chromosomes are pulled apart/away to opposite sides of the cell. |
Prophase | arrow_right_alt | The step of Mitosis when two nuclei are formed. |
Telophase | arrow_right_alt | The step of Mitosis when the chromosomes line up in the middle of the cell. |
Anaphase | arrow_right_alt | The step of Mitosis when the chromosomes become packed/condensed and are visible. |
Christian is observing some cells under the microscope and made the following observations:
No visible nucleus
Spindle fibers are present
Chromosomes are lined up in the center

A student observes a cell under the microscope and records their observations:
Two nuclei are visible and forming.
Spindle fibers are breaking down and almost gone.
The cell has not split yet.
