Viruses

Front

What are viruses considered to be nonliving?

Back

Viruses are considered nonliving because they are not made of cells, cannot reproduce on their own, and do not exchange gases.

Front

How do viruses differ from living organisms?

Back

Viruses are non-living because they cannot reproduce on their own, while living organisms can.

Front

What is a bacteriophage?

Back

A bacteriophage is a type of virus that specifically infects bacterial cells.

Front

Why do viruses need a host cell?

Back

Viruses need a host cell to reproduce, as they cannot replicate independently.

Front

What common feature do viruses and animal cells share?

Back

Both viruses and animal cells have genetic code in the form of nucleic acid.

Front

What is the structure of a virus?

Back

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

Front

Can viruses grow and develop?

Back

No, viruses do not grow and develop like living organisms; they can only replicate inside a host cell.

Front

What is the role of the capsid in a virus?

Back

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

Front

How do viruses reproduce?

Back

Viruses reproduce by infecting a host cell and using the host's cellular machinery to replicate their genetic material and produce new virus particles.

Front

What is the difference between a virus and a bacterium?

Back

Viruses are nonliving entities that require a host to reproduce, while bacteria are living organisms that can reproduce independently.
