- Sunlight. The leaves catch energy from the sun to power the whole process.
- Water. The roots drink water from the soil and carry it up to the leaves.
- Air. Tiny holes in the leaves take in carbon dioxide from the air.
- Food and oxygen. The leaf turns it all into sugar to eat and breathes out fresh oxygen for us.
