Study Notes
Microorganisms Overview
- Microorganisms typically include bacteria, viruses, fungi, and protozoa, often too small for human visibility without a microscope.
- These organisms are essential in various ecological and biological processes.
Taxonomic Classification
- A hierarchical taxonomic classification system is followed, which includes domains (such as Archaea, Bacteria, and Eukarya) and further subdivides into kingdoms, phyla, classes, orders, families, genera, and species.
Eukaryotic Microorganisms
- Eukaryotic microorganisms possess complex cells with a nucleus, including organisms such as fungi, protozoa, and some algae.
- They often have membrane-bound organelles, providing compartmentalization for cellular functions.
Prokaryotic Microorganisms
- Prokaryotic microorganisms consist of simpler cells without a nucleus, primarily including bacteria and archaea.
- These cells are generally smaller in size and lack the membrane-bound organelles found in eukaryotes.
Acellular Microorganisms
- Acellular microorganisms, or non-living entities, include viruses and prions.
- They cannot reproduce independently and require a host cell for replication, highlighting their unique status in biological classification.
