biodiversity- microbes Flashcards
kingdom
Highest formal category in the hierarchy of taxonomic classification, above phylum or division. (Kingdoms may be grouped informally into domains.)
monera
(in the five-kingdom system of taxonomic classification) the kingdom of prokaryotic organisms that include the bacteria and typically reproduce by asexual budding or fission, and that are nourished through photosynthesis or chemosynthesis.
prokaryote
Unicellular or multicellular organisms in the domains Bacteria and Archaea comprising small cells with the plasma membrane encased within a cell wall. The DNA exists as a circular strand, coiled within the cell.
heterotrophic
Organism that obtains energy by ingesting autotrophs or other heterotrophs and accessing the energy stored in the bonds of their organic molecules.
autotrophic
Organism with the capacity to make its own food.
bacteria
Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet’s ecosystems. Some species can live under extreme conditions of temperature and pressure.
archaea
One of the two main domains of prokaryotes, the other being bacteria.
virus
Infectious particle of protein and nucleic acid.
