Prokaryotic cells contain which external structure, whose function is to provide the cell with movement?
What is flagella?
TRUE OR FALSE:
A flagella’s rotation is reversible
What is TRUE?
A flagella’s rotation may be either clockwise or counterclockwise
Which type of cell wall stains purple and which type stains pink?
Gram + cell wall: stains PURPLE
Gram - cell wall: stains PINK

Prokaryotic cells are larger than eukaryotic cells
What is FALSE?
Prokaryotic cells are usually ~ 1.0 micrometer in diameter, while eukaryotic cells are about 10-100 micrometers in diameter.
Explain runs vs. tumbles
Runs: movement of cell in single direction for some time; increase with favorable stimuli
Tumbles: abrupt, random, changes in direction; increase with unfavorable stimuli
