Cells and Viruses: A Comparative Quiz

What is a key structural difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.

• Prokaryotic cells have a cell wall, while eukaryotic cells do not.

• Eukaryotic cells have ribosomes, while prokaryotic cells do not.

Which of the following best describes the complexity of eukaryotic cells compared to prokaryotic cells?

• Eukaryotic cells are generally simpler than prokaryotic cells.

• Eukaryotic cells are more complex due to their larger size and organelles.

• Prokaryotic cells are more complex due to their ability to survive in extreme environments.

• Both cell types have the same level of complexity.

How do scientific explanations for cellular complexity differ between prokaryotic and eukaryotic cells?

• Prokaryotic cells are explained by endosymbiotic theory, while eukaryotic cells are not.

• Eukaryotic cells are explained by endosymbiotic theory, while prokaryotic cells are not.

• Both cell types are explained by the same scientific theories.

• There are no scientific explanations for cellular complexity.

Which of the following is a characteristic of prokaryotic cells?

• Presence of a nucleus

• Presence of mitochondria

• Circular DNA

• Linear chromosomes

What is one way viruses differ structurally from cells?

• Viruses have a cell membrane, while cells do not.

• Viruses contain ribosomes, while cells do not.

• Viruses lack cellular organelles, while cells have them.

• Viruses have a nucleus, while cells do not.

How do viruses spread and cause disease in host organisms?

• By directly dividing like cells

• By hijacking the host cell's machinery to replicate

• By producing their own energy and proteins

• By forming spores that grow into new viruses

Compare the replication process of viruses to that of cells.

• Both viruses and cells replicate independently.

• Viruses replicate by using host cells, while cells replicate through division.

• Cells replicate by using host cells, while viruses replicate independently.

• Both viruses and cells replicate by binary fission.

What is a common method by which viruses enter host cells?

• Through active transport

• By endocytosis

• By osmosis

• Through direct fusion with the cell membrane

Explain why viruses are not considered living organisms.

• They cannot reproduce on their own.

• They do not have DNA or RNA.

• They can survive without a host.

• They do not cause diseases.

Which of the following best describes how viruses can cause disease in humans?

• By directly attacking and destroying cells

• By producing toxins that harm the body

• By integrating into the host genome and disrupting normal function

• By competing with human cells for nutrients
