capsule around molecule maybe slim/loose or capsule tight
bacterial chromosome/nucleiod
inside composed of condensed dna molecule and genectic material for the cell
plasmid
double stranded DNA circles containing xtra genes
pilus
a elongate, hollow appendage used in transfers of DNA to other cells (mating)
ribosomes
tiny particles composed of protien and RNA that are the sites of protien synthesis
actin cytoskeleton
long fibers of proteins that encircle the cell just inside the cell membrane and contribute to the shape of the cell
flagellum
specialized appendages attached to the cell by a basal body that holds a long rotating filament . the movement pushes the cell forward and provides motility
fimbriae
fine hairlike bristle extending from the cell surface that help in adhesions to other cells and surfaces (attachement )
inclusions/granuole
stored nutrients such as fat, glycogen desposited in dense crystals or particles that can be tapped into
cell wall
a semi rigid casing that provides structure and support the shape for the cell
cell memebrane
a thin sheet of lipid and protein that surrounds the cytoplasm and controls the flow of material into and out of the cell pool
outer membrane
extra memebrane similar to cell membrane also contains lipopoy saccaride.
controls flow of materialand portoions of it
endospores
dormant bodies formed within some bacteria that allows for their survial in adverse conditions
cytoplasm
water based system that fills the entire cell
flagella parts
filament , hook, basal body
monotrichous
single flagellum
lophotrichous
small bunches from the same site
amphitrichous
flagella at bothy poles
peritrichous
flagella disperedrandomly around the cell
chemotaxis-
movement positive-toward negative - aways
phototaxis
toward sunlight
slime layer
a loose sheild that protects some bacteria from loss of nutrients and water inportant in the formation of biofilms
capsule
a tightly bound gylcocalyx makes te cell wall thicker and denser protects against englufment by phagocytes
gram postive
has two layers
cell walls and cell membranec
gram negative
three layers
outer memebrance
cell wall
cell membrane
peptidoglycan
consists of glycan chains cross linked by short peptide fragments provides support
ribosomes
made of rna characterized by s unitis
prokaryotic ribosome is 70S
endospore forming bacteria
have to phase cycles
1st vegatative cell activily growing
2nd endospore formation
vegative cell undergoes a conversion to sporagium-sporagium to endospore
