Micro-organisms and unicellular organisms Microorganisms may be found almost anywhere in the Taxonomic structure. Unicellular organisms carry out all the functions of life. Bacteria and Archaea are almost always microscopic. A number of Eukaryote s are also microscopic, including most Protist s and a number of Fungi . Unicellular Species are those whose members consist of a single Cell throughout their life cycle. This latter qualification is significant since most Multicellular organisms consist of a single cell at the beginning of their life cycles. Usually, unicellular organisms contain only a single copy of their Genome (except when undergoing Cell Division ), although some organisms have multiple Cell Nuclei (see Coenocyte ). Habitats and ecology Microorganisms are found everywhere in nature. Even in hostile environments, like the Poles , Desert s, Geyser s, Rock s, and the Deep Sea , some types of microorganisms have adapted to the extreme conditions and sustained colonies; these organisms are known as Extremophiles . Some extremophiles have been known to survive for a prolonged time in a Vacuum , and some can be unusually resistant to Radiation . Microorganisms are used in Brewing , Baking , Biotechnology , recycling of other organisms' remains and waste products, and many other processes. They can also be harmful as Pathogen s when, as Parasite s, they cause Infection s. Microorganisms have an important place in all Ecosystems and in most higher-order multicellular organisms. For mankind they are important because they participate in the earth's element cycles (such as the Carbon Cycle ), and because of their use in the creation of certain types of Food , Medicines and Biological Weapons .
