Lesson summary
Lesson summary
- Photosynthesis is the process by which a plant makes glucose using sunlight and chlorophyll.
- Its equation is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
- It takes place in the chloroplasts. The oxygen released comes from the splitting of water.
- Its rate depends on light intensity, carbon dioxide concentration, temperature and the amount of chlorophyll.
- Photosynthesis is the basis of food on Earth and the source of the oxygen we breathe.
