archaea

Single-celled microorganisms that are prokaryotes and are genetically and biochemically distinct from bacteria, often found in extreme environments.
noun (plural)

This term refers to a specific domain of single-celled organisms. While they resemble bacteria in size and structure, they possess distinct molecular machinery, particularly in their cell membranes and genetic transcription processes, which makes them a separate evolutionary lineage.

Grammatically, this word is a plural noun derived from Greek. The singular form is "archaeon," though in scientific literature, the plural "archaea" is used overwhelmingly to describe the group as a whole.
