Periplasmic flagella are specifically for_________?
spirochetes
Where is the Periplasmic space located?
In gram negative bacteria right after the call membrane, before the call wall.
How do type IV fimbriae function?
mediate attachment to host epithelial tissues and a form of surface translocation called twitching motility
cytoplasm
Dense gelatinous solution comprised mainly of water an supplemented with dissolved gases, amino acids, sugars and salts.
nucleotide
Dense area of the cell where DNA is aggregated.
plasmids
extrachromosomal pieces of DNA
ribosomes
sites if protein synthesis
what do carboxysomes need for co2 fixation?
enzyme rubisco
cyanobacteria
pPhototrophs that produce food and oxygen for marine and freshwater ecosystems
thylakoids
