What is Aspergillus classified as?

  1. A species of yeast

  2. A species of mold

  3. A species of bacteria

  4. A species of virus

The correct answer is: A species of mold

Aspergillus is classified as a species of mold, which is a type of fungus. This classification is important because molds, including Aspergillus, play specific roles in various ecosystems, including decomposition and nutrient cycling. Understanding that Aspergillus is a mold helps in recognizing its characteristics, such as its filamentous structure and spore production. Molds differ from yeasts, which are single-celled fungi and generally reproduce by budding rather than by forming spores. Also, molds are distinct from bacteria, which are prokaryotic microorganisms that lack a defined nucleus, and viruses, which are not considered living organisms but rather infectious agents that require a host cell for replication. Knowing the classification of Aspergillus informs mold remediation professionals about the potential health impacts and the methods needed to control its growth effectively.
