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 plants and their defining tissues and major groups, describe their evolution and diversity, support identification and classification questions, and support botany learning.

A vascular plant, a member of the group of land plants with specialised conducting tissues, xylem and phloem, for transporting water and nutrients, comprising the lycophytes, ferns and their allies, gymnosperms and flowering plants, and including the vast majority of familiar plants from trees and grasses to succulents such as Echeveria and Delosperma; tracheophytes dominate terrestrial vegetation and are distinguished from bryophytes, which lack true vascular tissue.

What it is for: Plants with vascular tissue.

It can be explain vascular tissue and groups; describe evolution; support classification; support learning.

Distinguishing features

Xylem and phloem

Lignin

Sporophyte dominance

Terrestrial dominance

What it looks like

Trees, shrubs, herbs, ferns and conifers.

How it is recognised

Land plants with xylem and phloem

Lycophytes, ferns, gymnosperms, angiosperms

Bryophytes such as mosses lack true vascular tissue; algae are not land plants

What the second pass must settle

  • Should each major group be a separate entry?
  • How should classification databases be linked?
  • How should identification resources be linked?
