Amoeba Sisters' The Cell Cycle (and cancer)

Which statement is a core principle of Modern Cell Theory?

• All cells are identical in structure and function.

• All living things are composed of one or more cells.

• Cells can spontaneously generate from non-living matter.

• Only animals are made of cells.

How do multicellular organisms primarily increase in size?

• By individual cells growing larger indefinitely.

• By absorbing nutrients directly into their tissues.

• By making more cells through cell division.

• By converting non-living matter into new cells.

What is a primary characteristic of cancer cells?

• They divide less frequently than healthy cells.

• They are unable to absorb nutrients.

• They undergo uncontrolled and frequent division.

• They always remain anchored in their original location.

In which phase of the cell cycle do cells spend most of their time performing normal functions, growing, and replicating DNA, rather than actively dividing?

• Mitosis

• Cytokinesis

• Interphase

• Prophase

Are you enjoying the video lesson?

• Yes

• No

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

• G1, S, and M phases

• G1, S, and G2 phases

• S, G2, and M phases

• G1 and G2 phases only

What does the G1 checkpoint primarily assess before a cell proceeds to the S phase?

• Whether DNA has been correctly replicated.

• Whether chromosomes are properly aligned for separation.

• Whether the cell has grown sufficiently, has enough resources, and its DNA is undamaged.

• Whether the cell has completed mitosis.

What is the process by which a cell self-destructs if it is damaged beyond repair and cannot proceed through the cell cycle checkpoints?

• Mitosis

• Synthesis

• Apoptosis

• Cell Limbo

Which statement accurately describes cells in the G0 phase?

• Cells in G0 are actively dividing and replicating their DNA.

• Cells in G0 are permanently dormant and perform no cellular functions.

• Cells in G0 perform normal cellular functions but are not preparing to divide.

• Cells in G0 are undergoing programmed cell death.
