Factors Affecting Photosynthesis

HideShow resource information

There are several factors that may at any time limit the rate of photosynthesis:

  • temperature
  • carbon dioxide concentration
  • light intensity



1. As the temperature increases, so does the rate of photosynthesis. Temperature is limiting the rate of photosynthesis,

2. As the temperature approaches 45 degrees c, the rate of photosynthesis drops to zero. The enzymes controlling photosynthesis have been destroyed.


Carbon Dioxide Concentration

1. As the rate of carbon dioxide concentration increases, so does the
