What is considered the smallest complete form of life?

• A single DNA strand

• A protein case

• An individual cell

• A virus particle

What is the basic structure of a virus?

• A complete cell with organelles

• Genetic material enclosed in a protein case

• A multicellular organism

• A bacterium with a flagellum

How do viruses differ from bacteria in terms of cellular structure?

• Viruses are multicellular, while bacteria are unicellular.

• Viruses are made of cells, while bacteria are not.

• Viruses are not made of cells, while bacteria are unicellular organisms.

• Viruses have more complex cellular structures than bacteria.

How do viruses reproduce?

• They divide independently like bacteria.

• They grow and then split into new viruses.

• They require a host cell to be replicated.

• They produce waste products and then multiply.

Which of the following life processes do viruses NOT perform on their own?

• Having genetic material

• Reproducing

• Metabolizing and growing

• Causing infections

Despite having genetic material and being able to reproduce, why are viruses generally not considered alive?

• They are too small to be seen without a microscope.

• They cause diseases in other organisms.

• They lack cellular structure and cannot perform all life processes independently.

• They only infect animals, not plants.
