Let an agent explain vascular tissue, relay structure, function and evolution from plant biology sources, flag the misfiled alias, and distinguish vascular tissue from ground and dermal tissue, animal vascular systems, fruit layers such as the epicarp and non-vascular plants.

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 vascular tissue, relay structure, function and evolution from plant biology sources, flag the misfiled alias, and distinguish vascular tissue from ground and dermal tissue, animal vascular systems, fruit layers such as the epicarp and non-vascular plants.

The conducting tissue of vascular plants, comprising xylem, which transports water and dissolved minerals from roots upward and provides support, and phloem, which transports sugars and other organic compounds, arranged in vascular bundles and produced in woody plants by the vascular cambium; vascular tissue allowed plants such as ferns, conifers and flowering plants to grow tall on land. The registry alias epicarp names the outer layer of a fruit wall, which is not vascular tissue, and appears misfiled.

What it is for: Transporting water, minerals and sugars in plants.

It can be explain structure and function; relay evolution; flag misfiled aliases; distinguish related tissues.

Distinguishing features

Xylem and phloem

Long-distance transport

Structural support

Land plant innovation

What it looks like

Visible as veins in leaves, strings in celery and growth rings in wood.

Physical character

xylem cells: tracheids and vessel elements list

phloem cells: sieve elements and companion cells list

earliest vascular plants: Silurian, about 430 million years ago note - approximate

How it is recognised

Conducting tissue of plants, xylem and phloem

Xylem, phloem, vascular bundle, epicarp

Ground tissue stores and photosynthesises; dermal tissue covers; animal blood vessels are different; the epicarp is fruit skin

What the second pass must settle

  • The registry alias epicarp should be moved to fruit anatomy
  • How should plant biology sources be linked?
  • Should vascular cambium be a separate entry?
