Which branch of biology deals with the study of microorganisms?

Microbiology is the branch of biology dedicated to the study of microorganisms, which include bacteria, viruses, fungi, and protozoa. This field encompasses various aspects such as the physiology, genetics, ecology, and interactions of these tiny organisms with their environments and hosts. Microbiologists explore how microorganisms affect human health, agriculture, ecosystems, and even the biotechnology industry.

In contrast, zoology focuses on the study of animals, including their behavior, physiology, and classification. Botany is concerned with plant biology, examining the structure, processes, and ecological importance of plants. Genetics involves the study of heredity and the variation of inherited characteristics, primarily at the molecular level. Each of these fields specializes in distinct groups of organisms or processes, making microbiology uniquely central to understanding the vast world of microorganisms.
