Content: The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis. Chlorophyll looks green because it absorbs red and blue light, making these colours unavailable to be seen by our eyes. It is the green light which is not absorbed that finally reaches our eyes, making the chlorophyll appear green. Factors affecting Photosynthesis
For a constant rate of photosynthesis, various factors are needed at an optimum level. Here are some of the factors affecting photosynthesis. Light Intensity: An increased light intensity leads to a high rate of photosynthesis and a low light intensity would mean low rate of photosynthesis. Concentration of CO 2: Higher carbon dioxide concentration increases the rate of photosynthesis.
