An investigation to find out the effect of light on photosynthesis Aim: to find out if light affects the rate of photosynthesis. Theory Carbon dioxide + water light + chlorophyll glucose + oxygen 6co2 + 6h2o c6h12o6 + 6o2 Photosynthesis is a chemical reaction in which plants use carbon dioxide, water, light energy and chlorophyll to create glucose and oxygen for their food. Limiting factors * Low temperature * Shortage of carbon dioxide * Shortage of light * Chlorophyll * Water Temperature Temperature is a limiting factor; as the temperature increases the particles move faster which makes them collide more. Thus causing more successful reactions and the rate Is made faster. Carbon dioxide Carbon dioxide is needed for the equation to work and is needed to create glucose. Light Light is needed in photosynthesis to provide the initial energy to start the equation off. Chlorophyll Chlorophyll is needed as it us a green pigment which traps the sunlight to help the...
