microorganism : an organism (as a bacterium or protozoan) of microscopic or ultra-microscopic size (microorganism, 2015) [1]blank.gifWebster | Free | OneLook | Visuwords
Microorganism is a microscopic living organism, which may be single celled or multicellular. The study of microorganisms is called microbiology, a subject that began with the discovery of microorganisms in 1674 by Antonie van Leeuwenhoek, using a microscope of his own design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some fungi, algae, and certain animals, such as rotifers.
