Bacteria are formally classified by ? relationships and ? characteristics
|
phylogenic
phenotypic |
|
Medical identification of pathogens uses an ? system of classification based on ? stain,?, ? reactions, and ? requirements
|
informal
gram morphology biochemical metabolic |
|
A bacterial species is loosely defined as a collection of bacterial cells that shares an overall ? pattern of traits different from other groups of bacteria
|
similar
|
|
Variant forms within a species are called ? and include strains and ?
|

|
Bergey's Manual of Determinative Bacteriology is based solely on ? traits
|
phenotypic
|
|
Bergey's manual of systematic bacteriology that is based on ? and ? sequencing information
|
phenotypic and rRNA
|
|
Many microbiologist prefer an ? working system like ? stains to determine what type of bacteria they are dealing with.
|
informal
gram |
|
Gram stains in a lab allow for easily performed(accessible) morphological and physiological tests rather than ? relationships, that take longer to perform
|
phylogenetic
|
|
Bacteria don't exhibit a typical mode of sexual reproduction, they reproduce by ? fission which is making ? of themselves ?

thylakoids
chlorophyll a |
|
Cyanobacteria have ? inclusions that permit them to float on water surfaces and ? that convert ? nitrogen into a form usable by plants
|
