protist
Let an agent explain protists as an informal grouping, describe major lineages and current classification, relay their ecological, medical and economic significance, and distinguish protists from bacteria, fungi and true plants and animals.
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 protists as an informal grouping, describe major lineages and current classification, relay their ecological, medical and economic significance, and distinguish protists from bacteria, fungi and true plants and animals.
Any eukaryotic organism that is not an animal, plant or fungus, an informal grouping of mostly unicellular organisms spanning many lineages including algae, protozoa, slime moulds, water moulds and other fungus-like protists, carnivorous protists that feed on other cells, and marine protists that drive ocean food webs; the kingdom Protista is no longer accepted as a natural group, and protists are now classified into supergroups such as SAR, Archaeplastida, Amoebozoa and Excavata.
What it is for: Not applicable; a grouping of organisms.
It can be explain the grouping and classification; describe major lineages; relay ecological and medical significance; distinguish from other groups.
Distinguishing features
Paraphyletic grouping
Mostly unicellular
Great diversity
Supergroup classification
What it looks like
Mostly microscopic single cells; some visible as algae, slime moulds or kelp.
Physical character
described species: over 100000 count - estimates
share of ocean primary production: about half fraction - by marine protists and cyanobacteria
How it is recognised
Eukaryotes outside animals, plants and fungi
Algae, protozoa, slime moulds, water moulds, marine protists
Bacteria and archaea are prokaryotes; fungi and plants are separate kingdoms

- How should classification databases be linked?
- The registry entry has merged aliases naming subgroups and ecological categories; should they be split off?
