- Includes a diverse group of simple life forms, including bacteria, archaea, fungi, algae, protozoa, and viruses.
Organisms in Microbiology
- Bacteriology: The study of bacteria.
- Phycology: The study of algae.
- Parasitology: The study of parasites.
- Mycology: The study of yeasts and molds.
- Virology: The study of viruses.
Classification of Microorganisms
Cellular Organisms
- Prokaryotes:
- Lack a nucleus and membrane-bound organelles.
- Simpler structure, including bacteria and archaea.
- Eukaryotes:
- Possess a true nucleus and many membrane-bound organelles.
- More complex structure, including algae, protozoa, fungi, plants, animals, and humans.
Acellular Organisms
- Non-cellular entities that lack a cell membrane.
- Composed of genetic material protected by a protein coat, such as viruses.
- Can only live and reproduce inside a host cell.
