Domains and Kingdoms Flashcards

Vocabulary flashcards reviewing cellular organization, the three domains, and the six kingdoms of life.

Prokaryote

A single-celled organism that does not contain membrane-bound organelles.

Eukaryote

Any organism whose cells contain membrane bound organelles; can be single-celled or multicellular.

Domain

The highest taxonomic level, consisting of three groups: Eubacteria, Archaea, and Eukaryotes.

Carl Woese's Three Domains of Life

Eubacteria, Archaea, and Eukaryotes.

Kingdom Eubacteria

A kingdom of prokaryotes whose cell walls contain a unique compound, reproduce asexually, and comprise over 10,000 described species.

Kingdom Archaea

A kingdom of prokaryotes with unique cell wall and membrane structures. Found in extreme environments or animal digestive tracts.

Kingdom Protista

The most diverse eukaryotic kingdom, consisting mostly of unicellular organisms and multicellular species. Only kingdom that does not represent a single clade.

Amoebozoa

A group of amoeboid protists closely related to fungi and animals than to algae.

Extreme Thermophiles

Organisms belonging to the domain Archaea that thrive in environments with extremely high temperatures.
