PhotosynthesisrequiresChlorophyllEstablished
Photosynthesis requires chlorophyll.
Mechanism: Chlorophyll is the pigment that actually absorbs light energy and feeds it into the reaction.
- Campbell Biology — demonstrates this case · verified · moderate evidence · Chlorophyll is the primary pigment that captures light energy. (10 — Photosynthesis)

How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Chlorophyll is studied in this field.
What it looks like
Concrete cases that make this idea recognisable in the real world.
Why leaves change colour in autumn
In autumn, trees stop making chlorophyll and it breaks down. As the green fades, it reveals the yellow and orange pigments that were in the leaf all along.
Where you'll meet it
Journeys that walk you through this idea. You may recognise it from more than one.
Chlorophyll is the pigment that makes leaves green. It absorbs mostly red and blue light and passes that energy into the photosynthesis reactions.
- Connects 1 other ideas across 4 disciplines.
