What is the role of the flagellum?
Allows for swimming/movement
What do bacteria form in difficult conditions?

What bacteria doesn’t require oxygen to survive?
Obligate anaerobic bacteria
What bacteria can respire with or without oxygen?
Facultative anaerobic bacteria
Define sterile.
Free of all microorganisms
Define Asepsis.
Free of all pathogens
What are the steps of binary fission?
- DNA replicates, 2. Cell elongates, replicated DNA splits, 3. Replicated DNA moves to either side of the cell, cell wall & cell membrane begin to grow inward, 4. Two identical new bacterial cells formed
What are the steps of endospore formation?
- DNA replication, 2. Thick wall encloses DNA, 3. Cytoplasm shrinks and loses H2O, and remains dormant
What is a tough, thick-walled, dormant, and dehydrated bacterial cell formed during adverse conditions?
Endospore
