An experiment to determine the effect of light intensity on photosynthesis Aim In this experiment, I intend to alter the light intensity and measure its effect on photosynthesis through the production of oxygen Introduction Photosynthesis is the process by which green plants provide a source of energy for respiration. The formula is as follows- Carbon dioxide + water Carbon dioxide and water are chemically combined to produce glucose (the energy source) and oxygen (a waste product). Since it is impossible to measure the uptake of carbon dioxide in school laboratory conditions and water uptake is not an accurate measure of photosynthesis due to the loss of water through the stomata in transpiration, I will need to measure the products in order to have an idea of the rate of photosynthesis. Glucose is stored within the plant and is therefore not a feasible way of measuring photosynthetic rate. However oxygen is released as a waste gas through the...
