Introduction:
Photosynthesis is the trapping of carbon dioxide and its subsequent reduction to carbohydrate, using hydrogen from water. Hexose sugars and starch are commonly formed so the following equation is often used:
light energy
6CO2 + 6H2O  C6H12O6 + 6O2
carbon dioxide water chlorophyll carbohydrate oxygen
Photosynthesis consists of two stages: These are the light-dependent reactions, for which light energy is necessary, and the light independent reactions
series of light-dependent reactions that are

producing more oxygen meant that they would rise faster. Oxygen being a by-product of photosynthesis can be used to get a picture of the rate of photosynthesis of a plant. So ideally an experiment carried out measure the amount of this oxygen production would be better designed to get an indication of the rate of photosynthesis of a plant. The oxygen collection would take place in water; a water bath could be used for example.
