What are the factors that affect the rate of Photosynthesis?

Photosynthesis is the opposite of respiration. In this process we put in energy (through sunlight) to generate glucose.There are three factors that limit rate of photosynthesis: Light intensity, Carbon dioxide concentration, Temperature.The factor which is most limited (least available) at the time is the one that is rate limiting; so if that factor increases then photosynthesis rate increases.
