Structure of Bacterial Cell
Flagellum
Thin filament(s) found singly or in tufts used for motility.
Plasmid
Double-stranded DNA circle containing extra genes.
Bacterial Microcompartments
Protein coated packet containing enzymes/proteins.
Inclusion/Granule
Stored nutrients (fat, phosphate or gylcogen)
in dense granules.
Capsule
Outermost layer serving protective, adhesive and receptor type functions.
Pilus
Appendage for attachment
to another bacteria, used to transfer DNA.
Actin Cytoskeleton
Long supportive protein fibers inside cell membrane.
Cell Wall
Semirigid casing that provides structural support.
Outer Membrane
Extra membrane containing lipopolysaccharide found in some bacterial.
Fimbriae
Fine, hairlike bristles extending from cell surface for adhesion.
S Layer
Monolayer of protein used for protection and/or attachment.
Cytoplasm
Water-based solution filling the entire cell.
Ribosomes
The site of protein synthesis; made of protein & rRNa.
Bacterial Chromosomeor Nucleoid
Condensed circular DNA; contains instructions for making all bacterial proteins.
Cell (cytoplasmic) Membrane
The phospholipid bilayer and protein membrane that surrounds the cytoplasm.
