Students use the gas sensors to measure the amounts of oxygen and carbon dioxide consumed or produced by a plant during respiration and photosynthesis. They also determine the rate of respiration and photosynthesis in a plant.
Photosynthesis and respiration rates are studied using leaves from a plant in a respiration chamber connected to an oxygen and a carbon dioxide sensor in light for 10 minutes. This is the oxygen-time graph.
Linear regression is used to calculate the rate that carbon dioxide was either produced or consumed in light.
Photosynthesis and respiration during 10 minutes of dark are also studied and compared with the results obtained in the light.
