This image shows clusters of a coccus bacterium, known as Sarcina Lutea, deposited on a mica substrate. Note the large number of organisms that can fit in such a small area. The width of this image is about the breadth of two human hair. What shape does a coccus bacterium assume? How many organisms are there in this image? More information can be found in the Biofilms: What is that in your Dogdish module on this site. This image was taken using an Atomic Force Microscope (AFM). The shading of this image represents the height of objects (white is highest).
