Abstract

The bacteria are probably the simplest cellular organisms. Individual bacteria are visible only under a microscope and measure less than .8 µm in length and as small as 0.5 µm wide. However, the weight of the total number of bacteria in the world exceeds that of all other organisms. It has been calculated that there may be 1000000 to 50000000 bacteria per gram of top soil.
