Study Notes
Photosynthesis
- Photosynthesis is the process by which plants use light energy for growth.
- It is an endothermic reaction that uses light energy to convert carbon dioxide and water into glucose and oxygen.
- Leaves contain chlorophyll which absorbs light energy.
- The word equation for photosynthesis is: carbon dioxide + water → glucose + oxygen.
- The chemical formula for carbon dioxide is CO2.
- The chemical formula for water is H2O.
- The chemical formula for glucose is C6H12O6.
- The chemical formula for oxygen is O2.
Factors Affecting Photosynthesis
- Light intensity: As light intensity increases, the rate of photosynthesis increases because the plant has more light energy to carry out the reaction, until it plateaus.
- Carbon dioxide levels: As the level of carbon dioxide increases, the rate of photosynthesis increases until it plateaus.
- Chlorophyll levels: Leaves with less chlorophyll will have a lower rate of photosynthesis because they can trap less light energy.
- Temperature: As temperature increases, the rate of photosynthesis increases until the enzymes involved denature and the rate of photosynthesis decreases.
