Photosynthesis Planning Photosynthesis is the building up of sugars using carbon dioxide and water as the raw materials. The energy for the process comes from light and a green pigment called chlorophyll allows the plant to transfer the energy from light to sugar. The chemical equation for this process is: 6CO2 + 6H2O › C6H12O6 + 6O2 + energy ˆ (Light & Chlorophyll needed) Plants can only photosynthesise during the day, as light is needed. The rate at which a plant photosynthesises depends on the conditions in which it is kept, in particular the light intensity, the amount of carbon dioxide available, the temperature and the amount of water available. In general the best conditions for photosynthesis are found in areas with long hours of sunshine, warmth and high rainfall. In this investigation, I will assess how light intensity affects the rate at which photosynthesis occurs. The rate of photosynthesis can be calculated by measuring the...
