Study Notes
Photosynthesis
Reactants
- Light energy is obtained from the sun
- Carbon Dioxide is absorbed from the air
- Water is absorbed from the soil
Process
- Carbon Dioxide enters the leaf through stomata (tiny openings on the underside of leaves)
- Water is absorbed by roots from the soil and transported to leaves via the xylem
- Light Energy is absorbed by chlorophyll in the chloroplasts, splitting water (H2O) into Hydrogen and Oxygen
Products
Glucose
- Used by the plant for energy and growth
- Stored as starch
Oxygen
- Released into the atmosphere
- Essential for the respiration of most living organisms
