This image shows the structure of a bacterium that was growing on the surface of a dog's drinking dish. Note the folding of the surface into evenly spaced trenches. This bacterium also has thin filaments (flagella) that gives it mobility in the water. How wide apart are the tranches separated? What might be the purpose of these structures? More information can be found in the Biofilms: What is that in your Dogdish module on this site. This image was obtained using an atomic force microscope (AFM).
