Experiment to Investigate the Rate of Photosynthesis In this experiment I will be investigating how the rate of photosynthesis changes when a plant is put under different light intensities. Photosynthesis is the process by which plants make their own food. They use carbon dioxide and water, and with sunlight energy, the make glucose and oxygen. Sunlight Carbon Dioxide + Water › Glucose + Oxygen Energy 6CO2 + 6H2O › C6H12O6 + 6O2 There are a number of factors that affect the rate of photosynthesis. The main ones are: ? Light Intensity - provides the energy required for the reaction to take place. ? Carbon Dioxide concentration - one of the reactants. ? Amount of water available - one of the reactants. ? Temperature - gives particles more energy so the activation energy is reached by more particles. ? The number of chloroplasts in the plant - the site where the reaction takes place. To make the experiment a fair...
