No membrane-bound organelles
Cell wall – protects the cell & gives it shape.
Outer membrane – protects the cell against some antibiotics (only present in some)C. Basic Structure
Spirilla3 basic shapes
• Cell Arrangements
– Diplo – cells are paired
– Staphylo – cells are in
– Strepto – cells are in
Three basic shapes of bacteria
Bacillus = rod shape
Coccus = round or spherical shape
Spirilla = spiral shape
