The Rate of Photosynthesis

The Rate of Photosynthesis

1. The rate of Photosynthesis is affect by the intensity of:

   • Light
   • Carbon Dioxide
   • Temperture
   • Water
     • When the plant short of water that it becomes the limiting factor in photosynthesis

2. Limiting Factor depend on the Conditions

   • Any of these three factors can become the limiting factor
     • It's stopping the photosynthesis from happening faster
   • Environmental Conditions
     • Light
     • In Winter it's often the Temperture
     • If it warm and bright enough then Carbon dioxide is usually the limiting factor

3. Three important Graphs of rate of Photosynthesis

   • Too little Carbon dioxide also shows it down
     • Carbon dioxide is one of the raw material need for photodyntheis
     • As the intensity the amount of carbon dioxide will only increase the rate of photosynthesis up to a point
       • The graph flatten off as the CO2 is no longer the limitng factor
   • Not enough light shows down the rate of photosynthesis
     • As the Light Level is rasied, the rate of photosynthesis increase steadily - but only at a certain point
       • Because another limiting factor has affect the rate of photosynthesis
       • Light is the energy need for photosynthesis
   • The Temperture has to be just right
     • If the temperture is the limiting factor
       • If it too low - the enzymes work more slowly
       • If too hot - the enzymes it need for photodynthesis and its othe reactions will be damaged

4. You can artificially create the ideal conditions for farming

   • The most common is the greenhouse
