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 …
