Outline the affect of temperature, light intensity, and carbon dioxide concentration on the rate of photosynthesis.

Carbon dioxide and light intensity have relatively the same affect on photosynthesis. With both, if they aren't present, there is no way for photosynthesis to occur. As both increase the rate of photosynthesis increases in a rather linear way. Eventually the chloroplast reaches maximum production and it doesn't matter how much more they increase because the chloroplast can't work any faster
Temperature has a different affect. As it increases originally the graph increases, then it peaks. After the peak, the rate takes a nosedive. As the temperature continues to increase, enzymes begin to denature. This curses the rate of photosynthesis to stop completely
