A prokaryotic cell wall provides all of the following except:
Allows food and nutrients in, while releasing wastes out
Prokaryotes that obtain energy from chemicals
Chemotrophs
Can remain viable and metabolically inactive during harsh conditions for years
Endospores
What factor does a prokaryote need to have in its DNA to create a sex pilus?
F
Can survive with or without oxygen
Facultative anaerobe
Less peptidoglycan
Gram-Negative Bacteria Characteristic
Loses the violet stain, leaving a red/pink color
Gram-Negative Bacteria Characteristic
Holds the violet stain, leaving a purple color
Gram-Positive Bacteria Characteristics
More peptidoglycan
Gram-Positive Bacteria Characteristics
Prokaryotes that require organic nutrients
Heterotrophs
Most prokaryotes can reproduce every 1-3:
Hours
Produces methane
Methanogen
Sex pili are used to connect two prokaryotes and to exchange:
Nucleic Acids
A prokaryote that is poisoned by oxygen and survives using fermentation
Obligate anaerobe
Can't survive with oxygen, is poisoned by oxygen
Obligate anaerobe
Creates it own energy by using sunlight
Photoautotroph
Uses light and organic sources as energy
Photoheterotroph
Small ring of DNA found in prokaryotes (not the bacterial chromosome)
Plasmid
What factor does a prokaryote need to have in its DNA to be antibiotic resistant?
R
Endotoxins are:
Released when a bacteria dies
Bacilli
Rod
Cocci
Round
Sprillia
Spiral
An ecological relationship in which two species live in close contact with a larger host and smaller symbiont
Symbiosis
The process by which genes move between bacteria and the viruses that infect the bacteria
Transduction
The process by which a prokaryote cell takes up and incorporates foreign DNA from its environment
Transformation
Can bacteria have more than one flagella?
Yes
Can the factor that allows for the creation of a sex pilus be transferable between bacteria?
Yes
A bacteria that can live in a high saline environment
