The Invisible World
These are the most diverse and abundant group of organisms on Earth.
What are bacteria?
These are not included among the three domains or five kingdoms of modern taxonomy because they are acellular.
What are viruses?
These are organisms without membrane-bound nuclei.
What are prokaryotes
This is a type of unicellular fungal microorganism used for making wine, beer, and bread.
What is yeast?
Using oil-degrading bacteria to clean up an oil spill is considered this.
What is bioremediation?
Antonie van Leeuwenhoek observed this group of microorganisms along with bacteria under his microscope and called them “animalicules” (little animals).
What are protozoa?
These intracellular parasites are generally made of DNA or RNA packed into a protein coat.
What is a virus
The cells of prokaryotic organisms lack this.
What is a nucleus?
Multicellular parasitic worms studied by microbiologists are called this.
What are helminths?
Microorganisms in soil providing usable Nitrogen to plants is considered this.
Nitrogen fixing
These are nonliving and require a host to reproduce.
What are viruses?
This type of acellular infectious agent is only known to infect plants and is a small, circular, single-stranded nucleic acid molecule.
What is a viroid?
Organisms of the same species with genetic variation are considered these.
What are strains of a species?
Plants and algae are very similar, however algae can be multicellular or this.
What is unicellular?
Although plants and fungi are very similar, fungi have the ability to harvest energy from decaying matter rather than performing this.
What is photosynthesis?
These prokaryotes are likely to be present in deep seawater.
What are archaea?
This infectious protein is known to cause neurodegenerative diseases in humans such as Creutzfeldt-Jakob disease (“mad cow disease”).
What is a prion?
These often thrive in extreme environments.
What are archaea?
These are multicellular or unicellular producers in an aquatic environment.
What are algae?
The correct format to format the scientific name of an organism following scientific nomenclature is to capitalize the this category, but not the name of the species. Example: Escherichia coli.
What is the genus?
While domain is the broadest category that groups organisms by cell types, this is the narrowest category in the taxonomic classification.
What is species?
SARS-CoV-2 (Covid-19) virus is considered this, not a microorganism.
What is a microbe?
Most of these prokaryotes have circular DNA.
What are bacteria?
These are a diverse group of unicellular eukaryotes that are motile (can move) & ingest organic materials as a food source.
What are protozoa?
Biologists can divide living organisms into two groups: autotrophs and heterotrophs, which differ in their method of obtaining this.
What is energy?
