• Ribosome

Both Prokaryotic cells and Eukaryotic cells contain: (select all that apply)

• Cytoplasm

• DNA

• Ribosomes

• Nuclei

Which organelle breaks down dead organelles in the cell?

• Centriole

• Microfibers

• Lysosome

• Golgi apparatus

A cell cannot transport proteins. What is the most likely cause of this?

• Ribosomes stopped producing proteins

• Mitochondria stopped making the energy needed to produce proteins

• RNA was not produced in the nucleus

• The rough ER has broken down

Which of the following classifies as a main difference between eukaryotic and prokaryotic cells?

• Prokaryotic cells are usually smaller than eukaryotic cells

• Eukaryotic cells are usually smaller than prokaryotic cells

• Eukaryotic cells contain no membrane bound organelles and Prokaryotic cells contain membrane bound organelles

• Prokaryotic cells reproduce via mitosis and Eukaryotic cells reproduce via binary fission.

A scientist removed the cell wall of a plant cell using an enzyme. What might happen next?

• The plant cell would not be able to control what goes into and out of the cell

• The plant cell will not be able to remove waste products

• The plant cell will not be able to capture sunlight to make food

• The plant cell will not be able to withstand pressure when filled with water.
