What is the difference between a spore and an endospore?

What kind of bacteria has a comma shape to it?

True or false: Gram + bacteria have less peptidoglycan that Gram - bacteria.
False; it is the opposite.
True
List the eukaryotic microorganisms.
fungi, slime molds, protozoa, algae
What is the working distance and how can we shorten this?
The working distance is the area between the stage and the lens, and we can shorten it with immersion oil.

What is the correct way to write a species name when typing?

c. square
d. single ball
C. Square
Name three structural things found inside of a bacterial cell.
plasmid, inclusions, nucleoid, ribosomes
What does the Kirby Bauer Assay say?
You want a larger zone of inhibition (ZOI) because that means the sterilization method is more effective the bigger the ZOI is.
True or False: Bacteria, archaea, and viruses are all considered to be prokaryotic cells.
False; viruses are not living and are therefore not prokaryotic or eukaryotic.
What are two setbacks to brightfield microscopy?
1. You must be working with microorganisms that are small enough for light to pass through.
2. You have to stain the microorganisms, which kills the cells.
What is the difference between a spirillum and a spirochete?
