Stuart Shepherd 10PLB Ms O'Reilly Investigation of what affects the production of starch in plants Aim To discover whether light affects the production of starch in a plant. Information Green plants use energy from light to make carbon dioxide and water into food. This process is called photosynthesis. Green plants also produce oxygen during photosynthesis. Carbon dioxide (CO2) is a gas found in the air. During photosynthesis, CO2 is combined with water (H2O) to make glucose and oxygen. Glucose is the sugar that plants use for food. Plants store glucose by converting it into starch. Glucose is soluble and in a high concentration could damage could damage the plant, so the plant converts unused glucose into starch, which is stored in the cytoplasm of the plant. Starch molecules are long strings of glucose. The Photosynthesis word and chemical equations are as follows: Carbon Dioxide + water + light energy --> glucose + oxygen 6CO2 + 6H2O (+ light...
