Are bacteria classed as plants or animals?
None of the scientists believe that bacteria should be classified in the animal kingdom, and some suspect that the tiny organisms are not plants either. Hence, some classify them as plants and some place them in an in between kingdom of their own. But let’s not blame the experts for this confusion. After all, the average bacterium measures only a couple of microns or so and there are 25,400 microns to the inch. Bacteria come in hundreds of different varieties and together they outnumber all other living things in the world. They thrive everywhere from the deep ocean to miles up in the atmosphere. There are about 100 bacteria in the average cubic foot of ordinary air. Where ever we go, we cannot escape them and neither can anything else on the earth. The trouble in studying and classifying the bacteria is their infinitesimal size. Usually they are measured by the micron. Most of the bacteria types range between half a micron and ten microns. Their various shapes may be squiggles or rods
