- Stored in seeds
- Protienes
- Require Nitrogen also
- From soil

- Carbon dioxide + water ----> Glucose + Oxygen
- Plants
- Pondweed
- Algae
- Carbon Dioxide absorbed by stomata
- On the underside of the leaf
- Water absorbed by roots. Delivered to leaf via stem
- Can be 'limited'/ slowed down
- Light instensity
- Carbon Dioxide concentration
- Temperature
- Produces glucose for the plant
