A particular effector of photosynthesis is temperature. The optimum temperature for photosynthesis is 22-350C. At temperatures above 450C, photosynthesis in most plants ceases. For every 100C increase in temperature, the rate of photosynthesis increases about 2.2-2.6 times. Some bacteria and high-temperature blue-green algae can carry out photosynthesis at temperatures up to 700C.
