During photosynthesis, plants "fix" carbon dioxide to produce sugar (glucose). One of the by-products of this reaction is O2. An easy way to measure the rate of photosynthesis is to measure the release of oxygen by the plant, as oxygen release is directly related to the rate of photosynthesis.
Another way to measure the rate of photosynthesis is to measure the rate of carbohydrate production. When plants "fix" carbon dioxide, they produce glucose. If you measure the amount of glucose made by the plant, you measure the rate of photosynthesis.
