as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf, which changes the buoyancy--causing the disks to rise. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the net rate of photosynthesis.

photosynthesis between different types of plants. Methods One way of measuring the rate of photosynthesis is to monitor the rate of oxygen production by the plant. In strong light the rate of oxygen evolution from photosynthesis is in the order of 100 times its consumption by respiration so the latter process will not significantly interfere with
