Bacterial Basics
Viruses
Diagnosis
Immune System
100

This type of cell has no nucleus and includes bacteria.


prokaryotic cell

100

This is the protein coat of a virus.


capsid

100

A patient has a sore throat and bacteria are visible under a microscope.


bacterial infection

100

These are proteins made by the body to recognize and bind to specific pathogens.


antibodies

200

This structure helps bacteria move.


flagellum

200

Viruses must do this to reproduce.


infect a host cell

200

A doctor has prescribed antibiotics, but they don't seem to be working. 

viral infection

200

What is the main role of antibodies once they bind to a virus?


They mark the virus for destruction / neutralize it so it can’t infect cells

300

The process bacteria use to reproduce.


binary fission

300

This cycle immediately destroys the host cell.


lytic cycle

300

Would antibiotics treat the flu? Why or why not?


No, because flu is caused by a virus and antibiotics target bacteria

300

This type of cell produces antibodies.


B cells (WBC)

400

This style of bacterial growth shows rapid population increase.


exponential growth

400

Why are viruses not considered living? (give one reason)

They cannot reproduce independently/no metabolism/not made of cells

400

A patient stops antibiotics early. What is the risk?


Antibiotic resistance

400

Why can your body respond faster the second time you get the same infection?


Memory cells remember the pathogen and produce antibodies more quickly

500

Explain why antibiotics target bacteria but not viruses.


Bacteria have structures/processes (like cell walls, ribosomes) that antibiotics target; viruses do not.

500

What is a structural difference between a bacteriophage & the influenza virus? (not just the shape...)

Influenza virus has an envelope

500

Give TWO clues that would help you determine if an illness is bacterial or viral.


Possible Answers (but could vary): presence of cells, reproduction method, response to antibiotics, etc.

500

Explain how vaccines use the immune system to protect against viruses.


Vaccines introduce a harmless version or piece of the virus, allowing the body to produce antibodies and memory cells without causing illness
