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 cells by type, structure, function, division and study methods, and separate other senses of cell.

The basic structural and functional unit of all known living organisms, enclosed by a membrane and containing genetic material; cells are prokaryotic, as in bacteria and archaea, or eukaryotic, with a nucleus and organelles, as in plants, animals and fungi, and all cells arise from pre-existing cells.

What it is for: Biology, medicine and biotechnology.

It can be compare prokaryotic and eukaryotic cells; describe organelles and their functions; explain cell division; separate other senses of cell.

Distinguishing features

Membrane-bound

Contains DNA

Arises from other cells

What it looks like

Microscopic units seen under light and electron microscopes, with membranes, nuclei and organelles.

How it is recognised

Membrane-bound units under a microscope

Nucleus in eukaryotic cells

  2. Which entry fits? action

What the second pass must settle

  • Should cell types be separate entries?
  • How should cell ontologies be linked?
  • How should other senses be split off?
