Chapter 13.2 The Cell Cycle and Cell Division

What is Interphase?

• structure that holds the sister chromatids together.

• the phase of the cell cycle in which the nucleus and its contents divide.

• the phase in which the cytoplasm and its contents divide.

• the period during the cell cycle of a cell’s growth and development.

What is a Centromere?

• structure that holds the sister chromatids together.

• the phase of the cell cycle in which the nucleus and its contents divide.

• the phase in which the cytoplasm and its contents divide.

• the period during the cell cycle of a cell’s growth and development.

What is Mitosis?

• structure that holds the sister chromatids together.

• the phase of the cell cycle in which the nucleus and its contents divide.

• the phase in which the cytoplasm and its contents divide.

• the period during the cell cycle of a cell’s growth and development.

What is Cytokinesis?

• structure that holds the sister chromatids together.

• the phase of the cell cycle in which the nucleus and its contents divide.

• the phase in which the cytoplasm and its contents divide.

• the period during the cell cycle of a cell’s growth and development.

What might happen if cytokinesis did not occur after mitosis?

• The cell becomes stronger because it has two sets of organelles.

• The cell becomes heavier because it has two sets of organelles.

• The cells would remain fused together and the new double cell would have duplicates of all parts.

• The cell becomes bigger because it has two sets of organelles.

During the cell cycle, the cell’s nucleus and its contents divide to create two ____________.

• organelles

• organisms

• identical daughter cells

• organs

Why is the cell cycle so important?

• because it helps for growth and develop

• because it replaces cells that are old or damaged

• because it produces new cells

• All of the above

Where does the cell spend most of its life?

• prophase

• anaphase

• interphase

• telophase

Interphase is followed by a shorter phase of the cell cycle called ____________.

• mitotic phase

• metaphase

• telophase

• Anaphase

What are the two stages of the Mitotic Phase?

• telophase and metaphase.

• mitosis and cytokinesis.

• anaphase and telophase

• telophase and anaphase.
