Cell Division and The Cell Cycle - Note Presentation

Multiple Choice

Which of the following best describes the significance of cell division in multicellular organisms?

• It allows organisms to grow and repair tissues.

• It helps organisms to move faster.

• It enables organisms to produce energy.

• It allows organisms to breathe underwater.

Multiple Choice

What is the main difference between cell division in prokaryotes and eukaryotes?

• Prokaryotes divide by mitosis, eukaryotes by binary fission

• Prokaryotes divide by binary fission, eukaryotes by mitosis

• Both use binary fission

• Both use mitosis

Multiple Choice

Which phases are part of interphase in the eukaryotic cell cycle?

• G1, S, G2

• Mitosis, Cytokinesis, G1

• S, Mitosis, G2

• G1, Cytokinesis, S

Multiple Choice

During which phase of interphase does the cell grow rapidly and make proteins needed for DNA replication?

• Gap 1 (G1)

• Synthesis (S)

• Gap 2 (G2)

• Mitosis

Multiple Choice

• Gap 1 (G1)

• Synthesis (S)

• Gap 2 (G2)

• Mitotic Phase (M)

Multiple Choice

Which of the following statements about cell cycle regulation is correct?

• The cell cycle is regulated by carbohydrates.

• Regulatory proteins ensure the cell completes the previous phase before moving on.

• Cells always move from one phase to the next without any regulation.

• Cell cycle regulation is not necessary for cell division.

Multiple Choice

What is the main function of the G1 checkpoint in cell cycle regulation?

• To check if DNA has been replicated properly

• To ensure all chromosomes are aligned at the mitotic plate

• To decide whether the cell should divide before entering S phase

• To split the cytoplasm during cytokinesis

Open Ended

What questions do you still have about cell division and the cell cycle after today's lesson?

Multiple Choice

What is one reason why cancerous cells can be harmful to the body?

• They divide much faster than normal cells and can damage tissues and organs.

• They help repair damaged DNA.

• They protect the body from radiation.

• They stop dividing when nutrients are low.
