morphology
the study of structure and form of bacteria
.2 to 2 micrometers
what are the size ranges of bacteria
sphere
what shape are true cocci
bean & cone
what shapes, other than round, can cocci take
micrococcus
arrangement of cocci where the bacteria cell is grouped with no other
diplococcus
arrangement of cocci with a pair of bacterial cells
pneumonia
with what disease is it common to see a diplococcus arrangement of bacteria
streptococcus
chains of cocci
sarcina
term for when chains of cocci divide in three planes, resulting in a cube shaped cell
rod
what shape are bacillus
diplobacilli
a pair of bacilli linked together
streptobacilli
a chain of linked bacilli
spirillum
a single helical bacteria cell
vibrio
this shape of bacteria is in the shape of a comma
spirochete
spiral shaped bacteria
spirillum
this shape of bacteria has a rigid wall & will often move by flagella
spirochete
this shape of bacteria is flexible & moves by small axial filaments
cell wall
this part of bacteria is made of layers, is sometimes referred to as an envelope
cell wall
this part of bacteria lies between the cytoplasmic membrane & the cell's capsule
cytoplasm
this is thought of as the protoplasmic material & is located within the cell membrane
cytoplasm
what part of the cell contains the mitochondria, endoplasmic reticulum, golgi apparatus, & other cell organelles
cell membrane
this is a type of semi-fluid found on the internal side of the cell wall
capsule
the outermost layer of the cell wall
thick capsule
bacteria exhibiting this feature are more virulent & tend to be more difficult to kill
endospore
this is a dormant form of a bacterial cell that resists drying, heat, sunlight, and many disinfectants
lockjaw, anthrax, botulism, gas gangrene
these 4 diseases are caused by spore forming bacteria

these organisms are capable of surviving in the absence of organic compounds
heterotrophic
these organisms use organic matter for energy and the synthesis of cell materials

this is responsible for lockjaw
obligate saprophytes
another name for strict saprophytes
obligate parasites

heterotrophic bacteria that only grow on other living organisms
facultative bacteria
heterotrophs that live and adapt in food conditions that may vary, sometimes on living & sometimes on dead tissue
