Prokaryotic structure - basic principle

Prokaryote - Bacillus bacteria

Prokaryote - Coccus bacteria

Prokaryote - Spirillum bacteria

Bacterial cell model Nucleoid - is the genetic material (DNA) that controls cellular activities and is located in the cytoplasm of a bacterium Cell wall - is a protective layer that is made of peptidoglycan Cytoplasmic membrane - membrane that regulates chemicals going in or coming out of the cell Outer membrane - typical of Gram negative bacteria Fimbria - to adhere to host or inanimate objects Ribosomes - help in protein synthesis Mesosomes - folded invaginations of plasma membranes that have key enzymes for cellular respiration Plasmids - small, circular DNA molecules that carry genes to benefit survival of the bacterium Flagella - for movement
