The diagram shows the major stages of the cell cycle and the percentage of time spent in each phase. Which statement best describes why a cell spends the majority of its time in interphase?

• The cell is growing and carrying out processes such as metabolism and DNA replication.

• The cell is aging and processes are stopping as lysosomes clear dead cell matter away.

• The cell needs time to synthesize spindle fibers to complete mitosis.

• The cell needs time to complete cytokinesis.

Which table best compares the events that occur during different stages of the cell cycle?

The images show a cell in various phases of mitosis. Which of these lists the phases in the order that they occur in mitosis?

• Z, Y, X, W

• X, W, Z, Y

• Z, X, W, Y

• X, Z, Y, W

A diagram of a process that occurs during one of the stages of the cell cycle is shown. Which answer choice best identifies the process illustrated and the stage of the cell cycle in which it occurs?

• Replication, Interphase

• Protein synthesis, Prophase

• Crossing over, Metaphase

• Cytokinesis, Anaphase

This model of the cell cycle includes two arrows that each represent a process in the cycle. What do the two arrows represent? Arrow 1 represents __________, and Arrow 2 represents __________.

• Cell Division

• DNA Replication
