Peptidoglycan is found only in the bacterial __________________.

• cell membrane
• cell wall
• endospore
• glycocalyx

Which microbe is MOST resistant to being killed?

• Gram - bacteria
• bacteria which produce capsules
• bacteria which produce endospores
• bacteria in biofilms

Bacteria having no flagella are unable to

• grow in nutrient agar
• form biofilms in nutrient agar
• move in nutrient agar
• reproduce in nutrient agar

Prokaryotes ___________ in that their cells.

• have a nucleus
• have membrane bound organelles
• lack nucleic acids
• lack a nucleus

This structure is resistant to heat, cold, drying out, chemicals, antibiotics, and radiation.

• Endospores
• Axial filaments
• Cell membrane
• Cell wall
• Cytoplasm

The function of this is similar to flagella except they wrap inside the cell.

• Axial filaments
• Cell membrane
• Cell wall
• Endospores

Bacterial movement from flagella occurs

• from the whipping movement of the flagellum
• from the rotation of the flagellum

Flagella allow bacteria to do all of the following EXCEPT

• Provide a fluid mosaic model of flexibility.
• Sense their environment
• Move from a less favorable environment to a more favorable environment
• Allows them to exhibit chemotaxis
• Allows them to exhibit phototaxis

Which tube has motile bacteria?

• The test tube to the left
• The test tube to the right

Which letter represents a bacterium with an amphitrichous flagella arrangement?

• A
• B
• C
• D
• None of the above
