Cell Division

How do multicellular organisms primarily grow in size?

• By individual cells increasing significantly in size.

• By making more cells through cell division.

• By cells absorbing more nutrients and expanding.

• By increasing the amount of cytoplasm within existing cells.

In which phase do cells spend the majority of their time, performing functions like growth and DNA replication?

• M phase

• Mitosis

• Interphase

• Cytokinesis

Which type of cell is known to undergo mitosis frequently, leading to its rapid growth?

• Neuron cells

• Hair follicle cells

• Muscle cells

• Stomach cells

Which of the following phases are part of Interphase in the cell cycle?

• G1, S, and G2

• M, G1, and S

• G2, M, and G0

• S, G0, and M

What is the primary event that occurs during the S phase of the cell cycle?

• The cell grows and prepares for mitosis.

• The cell replicates its DNA.

• The cell performs its normal functions without dividing.

• Chromosomes align at the metaphase plate.

What happens to a cell if it fails to meet the requirements at a checkpoint and the issue cannot be fixed?

• It enters a temporary resting phase called G0.

• It pauses in "Cell Limbo" until resources are available.

• It undergoes programmed cell death (apoptosis).

• It continues to divide, potentially leading to mutations.

Which type of molecules are primarily responsible for regulating the cell cycle, including allowing progression or causing pauses?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids
