Review Flashcard: Viruses

Front

What takes over a living cell's functions when a virus invades?

Back

The virus's genetic material takes over the cell's functions.

Front

Where do viruses reproduce?

Back

Viruses reproduce inside of a host cell.

Front

Why are viruses classified as non-living?

Back

Viruses are classified as non-living because they need a host's energy and do not have their own energy.

Front

What are viruses not made of that contributes to their classification as non-living?

Back

Viruses are not made of cells.

Front

What do viruses require to reproduce?

Back

Viruses require a host cell to reproduce.

Front

What is the basic structure of a virus?

Back

A virus typically consists of genetic material (DNA or RNA) surrounded by a protein coat called a capsid.

Front

How do viruses differ from living organisms in terms of metabolism?

Back

Viruses do not have metabolic processes; they rely on the host cell's machinery for energy and replication.

Front

What is a host cell?

Back

A host cell is a living cell that a virus infects to reproduce and carry out its life cycle.

Front

What is the role of the viral capsid?

Back

The viral capsid protects the viral genetic material and helps the virus attach to and enter host cells.

Front

Can viruses be treated with antibiotics?

Back

No, antibiotics are ineffective against viruses; antiviral medications are used instead.
