The name given to a factor that is preventing any increase in photosynthesis is called a "limiting factor." A limiting factor is any condition or resource that is in shortest supply and restricts the rate at which photosynthesis can occur, thus preventing any further increase in the rate of photosynthesis.
Common Limiting Factors of Photosynthesis
- Light intensity: Photosynthesis rate increases with light up to a point, but if light is insufficient, it limits the process.
- Carbon dioxide concentration: Low CO2 limits the Calvin cycle and the overall photosynthesis rate.
- Temperature: Enzyme activity involved in photosynthesis is temperature-dependent, and too low or too high temperature can limit the rate.
In summary, the factor that prevents any increase in photosynthesis is known as the limiting factor, which can be one of those environmental or internal conditions restricting the photosynthesis process from progressing faster.
