Light intensity, CO2 concentration, and temperature are factors that determine the rate of photosynthesis. Light intensity has no effect on the rate of photosynthesis. If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease. Light intensity has an impact on the rate of photosynthesis.
