plastid
Let an agent explain plastids and their types and functions, describe their endosymbiotic origin and genetics, relate plastids to agriculture and disease, and support learning.
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 plastids and their types and functions, describe their endosymbiotic origin and genetics, relate plastids to agriculture and disease, and support learning.
A membrane-bound organelle found in the cells of plants, algae and some other eukaryotes, derived from an ancient cyanobacterial endosymbiont and containing its own DNA, differentiating into forms such as chloroplasts for photosynthesis, amyloplasts storing starch, chromoplasts holding pigments, proplastids, gerontoplasts in ageing tissues, the apicoplast of malaria parasites and cyanelles; plastids are central to photosynthesis, storage and metabolism and are studied in cell biology and evolution.
What it is for: Organelles of plants and algae.
It can be explain types and functions; describe origin and genetics; relate to agriculture and disease; support learning.
