Differences Between Viruses and Bacteria

Ms J chem discusses viruses and bacteria, highlighting their differences. Viruses are submicroscopic, nonliving entities that require a host to replicate, consisting of a protein coat and nucleic acid. Bacteria are single-celled, living organisms that reproduce independently and contain organelles. The video concludes with a comparison, noting that bacteria are larger, self-reproducing, and metabolically active, unlike viruses.

What are viruses primarily composed of?

• Chloroplasts and vacuoles

• Mitochondria and ribosomes

• Protein coat and nucleic acid

• Cell wall and cytoplasm

Why are viruses considered nonliving?

• They cannot reproduce on their own

• They do not have a cell wall

• They do not have a nucleus

• They do not carry out metabolic processes

How do viruses derive their energy?

• From the host cell

• From water

• From sunlight

• From their own metabolic processes

What type of nucleic acid can viruses contain?

• Either DNA or RNA

• Neither DNA nor RNA

• Only DNA

• Only RNA

What is a key difference between viruses and bacteria in terms of reproduction?

• Bacteria cannot reproduce

• Viruses need a host to reproduce

• Bacteria need a host to reproduce

• Viruses can reproduce on their own

Which of the following is true about bacteria?

• They carry out metabolic processes

• They are considered nonliving

• They need a host to derive energy

• They do not have a cell wall

What do bacteria contain that viruses do not?

• Capsid

• Organelles

• Protein coat

• Nucleic acid

Which of the following statements is true about the size of bacteria compared to viruses?

• Bacteria are smaller than viruses

• Bacteria and viruses are the same size

• Bacteria are many times larger than viruses

• Bacteria are the same size as viruses
