meristem
Let an agent explain meristems, relay types, functions, regulation and applications from plant biology sources, describe the named meristems, and distinguish meristems from permanent tissues, animal stem cells, callus tissue and buds as organs.
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 meristems, relay types, functions, regulation and applications from plant biology sources, describe the named meristems, and distinguish meristems from permanent tissues, animal stem cells, callus tissue and buds as organs.
A plant tissue of undifferentiated, actively dividing cells that produces new cells for growth, including apical meristems at shoot and root tips, the shoot apical meristem forming leaves and stems and the root meristem extending roots, which give primary growth, primary meristems derived from them such as protoderm, ground meristem and procambium, which forms vascular tissue, and secondary or lateral meristems such as vascular cambium and cork cambium, which thicken stems and roots; intercalary meristems at nodes let grasses regrow after grazing. Meristem culture is used to propagate virus-free plants.
What it is for: Plant growth and organ formation.
It can be explain types and functions; relay regulation; describe named meristems; relay applications.
Distinguishing features
Cell division
Undifferentiated cells
Positional organisation
Lifelong growth
What it looks like
Small regions of densely packed cells at tips of shoots and roots and in rings within stems.
Physical character
WUSCHEL-CLAVATA feedback: regulates shoot meristem size note - Arabidopsis research
growth types: primary and secondary list
registry parent: plant tissue note
How it is recognised
Dividing undifferentiated plant tissue
Primary meristem, secondary meristem, shoot apical meristem, root meristem, apical meristem, procambium
Permanent tissues are differentiated; animal stem cells are in animals; callus is wound tissue; buds are organs containing meristems
