Microbiology encompasses the study of a wide range of microscopic organisms, including:
* Bacteria: Single-celled prokaryotes that play vital roles in ecosystems and human health.
* Archaea: Another group of single-celled prokaryotes that often thrive in extreme environments.
* Fungi: Eukaryotic organisms that include yeasts, molds, and mushrooms.
* Viruses: Non-cellular entities that require a host cell to reproduce.
* Protozoa: Single-celled eukaryotic organisms that can be free-living or parasitic.
* Algae: Photosynthetic eukaryotic organisms that can be single-celled or multicellular.
Microbiology plays a crucial role in various fields, including medicine, agriculture, biotechnology, and environmental science.
