Temperature
As temp. increases, so does rate of photosynthesis. Temp. limits rate of photosynthesis. As temp. approaches 45degrees celcius, rate of photosynthesis drops to 0 bc enzymes controlling photosynthesis have been destroyed
CO2 Concentration
As rate of CO2 concentration increases, so does rate of photosynthesis. CO2 limits rate of photosynthesis. After reaching a certain point, an increase in CO2 has no further effect. CO2 isn't the limiting factor - must be either lighting of temperature
Light Intensity
As light intensity increases, so does rate of photosynthesis. Light intensity limits rate of photosynthesis. After reaching a certain point, an increase in light intensity has no further effect.
