In this lab, you will be using leaf disks, to assay the net rate of photosynthesis under various lighting conditions leaf disks normally float, however when the air spaces are infiltrated with carbon dioxide, the overall density of the lead disk increases and the leaf disk sinks when sodium bicarbonate is added to the water, the. The purpose of this experiment was to observe the effect of varying carbon dioxide levels on the rate of photosynthesis by using the floating disk method described in the ap biology investigative labs textbook the floating disk method uses the oxygen by-product of photosynthesis to make sunken disks of leaves to float.
