Distinguish Between Viruses and Bacteria

Front

What is a virus?

Back

A virus is a microscopic infectious agent that requires a host cell to replicate and spread. It consists of genetic material (DNA or RNA) surrounded by a protein coat.

Front

What is bacteria?

Back

Bacteria are single-celled microorganisms that can live independently or in colonies. They have a simple cell structure and can reproduce by binary fission.

Front

What is the main difference in reproduction between bacteria and viruses?

Back

Bacteria reproduce independently by splitting into two (binary fission), while viruses require a host cell to reproduce.

Front

Do both bacteria and viruses contain genetic material?

Back

Yes, both bacteria and viruses contain genetic material, either DNA or RNA.

Front

Can antibiotics kill viruses?

Back

No, antibiotics are effective against bacteria but do not work on viruses.

Front

What structures do bacteria have that viruses do not?

Back

Bacteria have ribosomes and a cell membrane, while viruses lack these structures.

Front

How do viruses spread?

Back

Viruses spread by infecting host cells, often through direct contact, airborne transmission, or bodily fluids.

Front

What is the role of ribosomes in bacteria?

Back

Ribosomes in bacteria are responsible for protein synthesis, allowing them to carry out essential functions.

Front

What is binary fission?

Back

Binary fission is the process by which bacteria reproduce, where a single cell divides into two identical daughter cells.

Front

Can bacteria be treated with antibiotics?

Back

Yes, bacterial infections can be treated with antibiotics, which target specific bacterial functions.
