rate of photosynthesis

• how does light affect rate of photosynthesis?

  • increase in light intensity = steady increase of photosynthesis to a certain point
  • beyond will be temperature or CO2 as limiting factor
• how does carbon dioxide affect the rate of photosynthesis?

  • increasing CO2 will increase the rate up until a point
  • means limiting factor would then be light intensity or temperature
• how does temperature limit rate of photosynthesis?

  • temperature increase - increase rate up to a point
  • too high = plant enzyme to denature - rate rapidly decreases
