cytosol
what are the structures in bacteria
plasmids, ribosomes, cell membrane,
cell wall, capsual
what is the importance of bacteria’s capusle

binary fission
asexual reproduction by a separation of the body into two new bodies.
conjugation
the temporary union of two bacteria or unicellular organisms for the exchange of genetic material.
what are two foods made by bacteria
