Part 2: Rate of Photosynthesis Place the leaf of a tomato plant (which prefers full sun) into the plexiglass box. The leaf is still attached to its plant and
the opening around the stem is sealed to keep the box a closed system.
Change the intensity of the light by reducing the cheesecloth layer. At each light intensity, read the CO2 concentration
at the input and output tubes.
Then follow the same procedure for a shade-preferring oxalis plant.
Record the changes in CO2 for each plant at each light intensity in your Notebook
