Microorganisms

Definition

Microorganisms are tiny living organisms, often too small to be seen without a microscope, that include bacteria, viruses, fungi, and protozoa. During the Scientific Revolution, the study of microorganisms significantly advanced human understanding of disease and the natural world, laying the groundwork for modern microbiology and changing perceptions about health and illness.
