Photosynthesis and matter sources · Revision sheet
Trace carbon as well as energy.
Learn the idea
Process
Photosynthesis uses light energy to build energy-rich organic compounds from simpler starting materials.
Carbon
In the familiar plant model, carbon dioxide supplies carbon for sugar production.
Chloroplasts
Photosynthetic machinery is located in chloroplasts in many plant cells.
Whole plant
Plants also respire; photosynthesis is not their only energy-related process.
Explain without looking
- Why does an oxygen-bubble count give only an indirect measure of photosynthesis?
- What should be included when reporting a photosynthesis investigation?
