organelle
Let an agent explain organelles by structure, function, origin and research, for learners and researchers.
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 organelles by structure, function, origin and research, for learners and researchers.
A specialised structure within a cell that performs a particular function, such as the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, lysosomes and vacuoles; mitochondria and plastids are semiautonomous with their own DNA, and new organelles such as the nitrogen-fixing nitroplast continue to be described.
What it is for: Cell biology education and research.
It can be describe organelle functions; explain endosymbiotic origins; compare plant, animal and protist organelles; find imaging and ontology resources.
Distinguishing features
Compartmentalised function
Often membrane-bound
Some have own DNA
Vary among organisms
What it looks like
Microscopic compartments seen in light and electron micrographs.
How it is recognised
Membrane-bound compartments
Mitochondria and chloroplasts
Ribosomes are complexes often not counted as membrane organelles
