OBSERVNG BACTERIA Most bacteria are significantly smaller than the cyanobacteria. The bacteria are simple in form and anatomy and exhibit three basis shapes: bacillus (rod shaped), coccus (spherical – – shaped), and spirillum (spiral shaped). An electron microscope is used to observe the – anatomical detail of a typical bacterium.
