What kind of particles are viruses classified as?

Cellular organisms
Submicroscopic particles
Visible particles
Yeast spores

The correct answer is: Cellular organisms

Viruses are classified as cellular organisms. Unlike bacteria, viruses are not considered living organisms because they cannot carry out life processes without a host cell. Viruses are essentially genetic material (DNA or RNA) surrounded by a protein coat, lacking the cellular structures found in other living organisms. This distinction places viruses in a unique category separate from bacteria, fungi, or yeast spores, making option A the correct choice.
