prokaryotes
Let an agent explain prokaryotes, relay cell structure, diversity, ecology and classification debates from microbiology sources with attribution, describe the named groups, and distinguish prokaryotes from eukaryotes, viruses, Bacteria and Archaea as separate domains, and pathogens specifically.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain prokaryotes, relay cell structure, diversity, ecology and classification debates from microbiology sources with attribution, describe the named groups, and distinguish prokaryotes from eukaryotes, viruses, Bacteria and Archaea as separate domains, and pathogens specifically.
Single-celled organisms whose cells lack a membrane-bound nucleus, comprising the domains Bacteria and Archaea, the most abundant and metabolically diverse life on Earth, including groups such as methanotrophs that consume methane and marine prokaryotes that dominate ocean microbial communities; the term prokaryote reflects an older two-way division of life, and since Carl Woese s work in the 1970s many scientists regard Bacteria and Archaea as separate domains and question whether prokaryote is a natural group.
What it is for: Not applicable; a category of organisms.
It can be explain cell structure and diversity; relay classification debates; describe named groups; distinguish related categories.
Distinguishing features
No nucleus
Circular chromosomes typically
Enormous diversity
Contested term
What it looks like
Microscopic cells, typically spheres, rods or spirals, visible under a microscope.
Physical character
typical size: about 0.5-5 micrometres
three-domain system: 1977-1990 years - Woese and colleagues
estimated global prokaryote cells: about 10^30 count - Whitman et al. 1998
How it is recognised
Organisms without a cell nucleus
Methanotroph, marine prokaryotes, bacteria, archaea
Eukaryotes have nuclei; viruses are not cells; Bacteria and Archaea are distinct domains; only some prokaryotes cause disease
