BRAINCAKELimiting Factors of Photosynthesis
The rate of photosynthesis depends on several factors: light intensity, carbon dioxide concentration and temperature (water availability matters too, but water stress closes stomata before it limits the reactions directly).
A limiting factor is the factor that is in shortest supply and so limits the rate of a process. If the level of the limiting factor is increased, the rate increases. Increasing any other factor has no effect until the limiting factor is raised.
