Why is the rate of photosynthesis lower in green light?
This green light in the white light is the light that is not absorbed by the chlorophyll which makes the rate of photosynthesis of the leaf discs is lower than other leaf discs under other colors of light. After all the results were obtained, graphs were plotted by using all the data.
Why is respiration an indirect measurement of the net rate of photosynthesis?
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.

Why do leaf discs rise up during photosynthesis?
On the other hand, when the leaf discs were left in the beaker under the lamp, we had observed that the leaf discs slowly rise up to surface. The explanation for this is, when photosynthesis occur, oxygen will be released into the interior of the leaf causing the buoyancy to change.
