Temperature

Temperature also governs the rate: with plenty of light and CO2 already available, photosynthesis speeds up as temperature rises, up to a maximum rate, after which the rate falls or declines again. The optimum temperature range at which most plants photosynthesize fastest is about 25-30°C, though some plants are exceptional — Opuntia, for instance, can photosynthesize even at temperatures as high as 55°C, which is described as its maximum temperature; the minimum temperature, …
