Nucleoid
Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called
Plasma membrane
Embedded within the cytoplasm are small organelles composed of rRNA and protein called
that function in protein synthesis.
Flagella
Cell wall
Some prokaryotes, such as cyanobacteria, are photosynthetic and contain
to aid in photosynthesis.
Plasmids
Some bacteria contain appendages such as
, which are long whip-like structures to aid in locomotion; fimbriae, which are small bristle-like fibers to function in attachment; or conjugation pili, which are short tubular structures to aid in the exchange of genetic material.
