To determine the rates of photosynthesis for the 5-week-old bean plant and the 5-week-old corn plant, the QUBIT Systems, Inc. apparatus was employed. A diagram of this apparatus is presented in page 4-5 of the biology lab manual (Bio, 2002). The computer connected to this apparatus was adjusted to present two graphs which measure the percentage of Oxygen in the air over time and photon flux (micromole quanta/m^2/s). Next, a leaf was retrieved from the top of a bean plant and sealed from the air in the laboratory via thumbscrews inside the leaf chamber of the apparatus. Caution was used to ensure that the leaf was not placed directly beneath the oxygen sensor of the apparatus, since doing so would result in improper amount of surface area of the leaf being exposed to sunlight. To ensure that the leaf was not over heated by the lamp's...
