Lesson notes
Key points
- Plants perform photosynthesis, using sunlight to build sugar from carbon dioxide and water.
- It happens in chloroplasts, green structures packed with chlorophyll, the pigment that captures light.
- The carbon in that sugar becomes wood, leaves and cocoa pods, so the tree is built mostly from air.
Takeaway: Plants build themselves mostly out of air and sunlight.
