Understanding Cell Biology and Cancer

What is the basic unit of life according to cell theory?

• Organs

• Molecules

• Cells

• Atoms

How do multicellular organisms grow?

• By exercising

• By cell enlargement

• By cell division

• By absorbing nutrients

What is a common cause of cancer?

• Cells dying too quickly

• Cells dividing too slowly

• Cells not dividing

• Unregulated cell division

What is the role of mitosis in the cell cycle?

• Cell division

• Cell growth

• DNA replication

• Protein synthesis

Which is a treatment method for cancer?

• Increasing cell division

• Reducing nutrient supply

• Chemotherapy

• Promoting cell growth

What phase do cells spend most of their time in?

• Interphase

• G0 phase

• M phase

• S phase

What is the significance of checkpoints in the cell cycle?

• They replicate the cell's DNA

• They ensure cells are ready to proceed to the next phase

• They ensure cells divide at the correct time

• They prevent cells from dividing

What is apoptosis?

• Cell growth

• Cell division

• Cell death

• Cell mutation

Which phase is not part of the cell cycle's active phases?

• G1

• S

• G2

• G0

What can trigger apoptosis?

• Irreparable cell damage

• Successful cell division

• Proper DNA replication

• Adequate nutrient supply
