aim I aim to investigate the effects of the quantity of light and thus the light intensity on the rate of photosynthesis in Elodea. background Photosynthesis is the production of food compounds from carbon dioxide and water by green plants using energy from sunlight, absorbed by chlorophyll ie. photosynthesis is how plants feed. lightlightlil 6CO2 + 6H2O --> C6H12O6 + 6O2 Raw materials Products ie. Green plants make organic substances from inorganic substances. In order to keep the equation for photosynthesis simple, glucose is shown as the only food compound produced. However, this does not mean that glucose is not the only food compound produced. The process of taking in and giving out gases is known as gaseous exchange. When green plants photosynthesise, they take in CO2 and give out O2. This only happens in daylight when light is available as an energy supply. The exchange of gases in green plants in light is the opposite of that...
