Pro vs Eu Quiz 1

The diagram below shows a cell with DNA floating freely in the cytoplasm, a cell wall, ribosomes, and no visible nucleus or organelles. Based on this information, which of the following conclusions is most accurate?

• This cell is eukaryotic because it contains ribosomes and a cell wall.

• This cell is prokaryotic because it lacks membrane-bound organelles and a nucleus.

• This cell must be multicellular because it lacks mitochondria.

• This is a plant cell because it has a cell wall and no visible vacuole.

What evidence most strongly supports the scientific theory that mitochondria and chloroplasts originated from free-living prokaryotic cells?

• Both organelles contain ribosomes that make enzymes needed for photosynthesis.

• They are the only organelles found in multicellular eukaryotes.

• Mitochondria and chloroplasts have their own circular DNA and replicate independently of the cell.

• They both contribute to protein synthesis and transport.

A student observes a cell under a microscope. The cell has a cell wall, ribosomes, and free-floating circular DNA, but no nucleus or membrane-bound organelles. Question: Is the cell prokaryotic or eukaryotic? Explain your answer by identifying at least two structural features and how those features relate to the cell’s level of complexity.
