Limiting Factors & the Rate of Photosynthesis James Irwin Introduction Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen. For photosynthesis to take place a plant requires carbon dioxide, water, light, a suitable temperature, chlorophyll and availability of nutrients. The raw materials of photosynthesis are carbon dioxide and water. Carbon Dioxide is the only form in which a plant can take in carbon, however, in this case using an aquatic plant, in may obtain it from hydrogen carbonate ions in the water. The limiting factors of photosynthesis are: * Light Intensity If you put a plant in total darkness, it cannot photosynthesize at all. As the amount of light is increased, the rate of photosynthesis increases until the chloroplast is working at full capacity. At this level of light intensity, adding more light makes not difference to the rate of photosynthesis. In fact,...
