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
