Factors affecting photosynthesis

• Factors Affecting the Rate of Photosynthesis

  • Light intensity

  • Carbon dioxide concentration

  • Temperature

  
• Photosynthesis - Light Intensity


  • As light intensity increases, the rate of photosynthesis increases until a constant rate is reached

  • More light means more energy for photosynthesis

  
• Photosynthesis - Carbon Dioxide Concentration


  • As carbon dioxide concentration increases, the rate of photosynthesis increases until a constant rate is reached.

  • More carbon dioxide means more glucose can be produced.

  
• Photosynthesis - Temperature


  • As temperature increases to the optimum temperature, the rate of photosynthesis increases

  • As temperature increases beyond the optimum temperature, the rate of photosynthesis decreases
