Microbiology Study

Unicellular microorganisms consist of a single cell, while multicellular microorganisms are made up of complex cells. Acellular microorganisms lack cells altogether and are instead composed of viral particles or other non-cellular structures.

Microbiology encompasses sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology.

Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, while prokaryotic microorganisms lack membrane-bound organelles and include Bacteria and Archaea.

<p>The main challenge is that less than 1% of the microorganisms present in common environments can be cultured in isolation using current means, which limits the ability to fully understand and identify the diverse range of microorganisms.</p> Signup and view all the answers

<p>Microbiology encompasses sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Virology focuses on the study of viruses, bacteriology on bacteria, protistology on protists, mycology on fungi, immunology on the immune system, and parasitology on parasites.</p> Signup and view all the answers
