Bacteria are prokaryotes, meaning they ________.

• lack a nucleus

• are very large

• contain no DNA

• have a cytoplasm

What is a host?

• An organism that eats another organism

• An organism or a cell that the virus needs to reproduce in

• Something that causes harm to the cell

• The person that greats you at a resturant

Antibiotics work to cure viruses?

• True

• False

What do viruses need to reproduce?

• Genetic material

• A host cell

• Bacteria

• Insulin

The flagella on a bacteria serve what purpose? 

• helps the bacteria find a mate
• cleans the bacteria
• helps the bacteria to move
• protects the bacteria

Tiny structures that produce proteins inside bacteria

• bacteria

• ribosomes

• cytoplasm

• endospore

What is the first step of the virus reproduction cycle?

• The viruses genetic material (DNA) starts to take over the functions of the cell
• The host cell bursts open, releasing the new viruses
• The virus injects its genetic material into the cell
• A virus attaches to the surface of a host cell

What is the last step in the viral reproduction cycle?

• A virus attaches to the surface of a host cell
• The proteins and genetic material start to assemble in the cell
• The host cell bursts open, releasing the new viruses
• The virus injects its genetic material into the cell

Viruses are surrounded by a protein coat known as a

• Capsid

• Capsule

• Enzyme

• Nucleotide

viruses require a host to function because

• They can not reproduce on their own

• it makes it more fun

• they do not work as well as bacteria
