It has been suggested that the amount of living organisms below the Earth’s surface may be equivalent with the amount of life above the surface. Fungi can be split into three main groups, 1) moulds which display thread-like (filamentous) growth and multicellular structures, 2) yeasts which are typically non-filamentous and can be single celled and 3) mushrooms which possess a fruiting body for production of spores. Viruses are considered by many experts to not be living organisms. These are made with the help of microorganisms. The bacterium called lactobacillus reproduces in milk and helps convert milk into curd. Microbes called extremophiles have been isolated from rocks as much as seven kilometres below the Earth’s surface. Bacteria are the only microorganisms which can live harmlessly within the human body, often aiding bodily functions such as digestion.

Includes the study of microbial pathogenesis and epidemiology and is related to the study of disease pathology and immunology. No climate is too hot or too cold for microorganisms and no place is too wet or too dry. Emphasize that while most microorganisms are helpful, several microorganisms can cause disease, including bacteria, fungi, protozoa, and viruses. Bacteria, perhaps the most well-known microorganism, are a member of the prokaryotes; they have no nucleus within the cell and contain no organelles (specialised cellular ‘organs’). Two sources of energy are available to microorganisms. They spread communicable diseases, which can spread from an infected person to a healthy person. Name the groups in which microorganisms are broadly classified. Anton Van Leeuwenhoek discovered the first microbe in 1675. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from 6th century BC India.

Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. Microorganisms, as their name implies, are so small that they usually require a microscope to see. Microorganisms are also useful in other food-making processes like brewing, winemaking, baking and pickling. When you have flu or viral fever and you go to the doctor, you are usually given medicines called antibiotics. Some of these can make their own food, like plants do and are called autotrophic. Bacteria are extremely diverse and in terms of number are by far the most successful organism on Earth. They can be divided into six major types: bacteria, archaea, fungi, protozoa, algae, and viruses. Some microorganisms can cause disease in a host and are known as pathogens. A microorganism is a living thing that is too small to be seen with the naked eye. A virion (a virus particle) requires a host cell in order to replicate. There are tiny little organisms all around you, which are so small that it is impossible to see them with your naked eye.
