Bacterial shapes: Coccus, Bacillus, Pleomorphic

The three basic bacterial shapes are coccus (spherical), bacillus (rodshaped), and spiral (twisted), however pleomorphic bacteria can assume several shapes. Cocci (or coccus for a single cell) are round cells, sometimes slightly flattened when they are adjacent to one another. , bacteria, bacillus, coccus, pleomorphic, Microbiology, Genetics
