Aim My aim is to investigate the effect of changing light intensity on the rate of photosynthesis. Introduction This is an investigation into how the amount of light provided to a plant can affect the rate of photosynthesis in a plant when it has a constant supply of reactants. The reactants in this experiment are H2O(water), CO2(carbon dioxide) and light. The products are glucose and oxygen. The glucose is stored in the plant as starch and also used for respiration and growth of the plant. The oxygen is given off into the surroundings, this is what we will be measuring. The word equation for this process is: sunlight 6CO2 + 6H2O-----C6H12O6 + 6O2 There are several factors that affect the rate of photosynthesis- Temperature- the warmer the surroundings the higher the rate of photosynthesis. This is because this is an enzyme based process. This will happen only if the plant is given an adequate supply of...
