A microorganism is a tiny organism that can only be observed through a microscope. It is a unicellular living being.
Explanation:
Robert Hooke and Antonie van Leeuwenhoek are among the scientists who, in the seventeenth century, made the first observations of microorganisms thanks to the use of microscopes. Thus, over the years, it was possible to discover how milk is transformed into cheese and how grapes make it possible to obtain wine, for example. Leeuwenhoek is praised for his discoveries in the field of microbiology. He was born in 1632 and was a Dutch merchant who not only anticipated the others in the use of the microscope, but also improved his manufacturing techniques. Hooke, on the other hand, was a contemporary scientist, born in England and interested in several fields, among which were medicine and biology.
