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 photosynthesis and its mechanisms, distinguish oxygenic and anoxygenic forms, relate it to agriculture, climate and energy, and support learning.

The process by which plants, algae and some bacteria convert light energy into chemical energy, in oxygenic photosynthesis using water and carbon dioxide to make sugars and release oxygen, and in anoxygenic photosynthesis of certain bacteria using other electron donors; photosynthesis occurs in chloroplasts through light-dependent reactions and the Calvin cycle, supplies most of the biosphere with energy and oxygen, and is studied for agriculture, climate and energy.

What it is for: Converting light to chemical energy.

It can be explain mechanisms; distinguish forms; relate to agriculture and climate; support learning.

Distinguishing features

Light capture

Carbon fixation

Oxygen release in oxygenic form

Global significance

What it looks like

Not visible directly; green tissues in light.

How it is recognised

Light to chemical energy

Oxygenic or anoxygenic

Respiration releases energy from sugars instead
