M3 L1: Gizmo Simulation Lab: Photosynthesis - Honors Revised by NVLA: 10/15/2019 BIO 197 M3_L1_Gizmo_Simulation_Lab_ Photosynthesis_-_HONORS 2020 – University Of Nevada Name: Thao Ho Date: 6/16 What did you eat for breakfast, lunch, and dinner yesterday? Imagine that your body made its own food, internally. Sound crazy? Plants do this all the time. Plants make their own food in a process called photosynthesis. In photosynthesis, plants use sunlight, carbon dioxide (CO2), and water (H2O) to make sugars, which provide them with the energy they need to live as well as the raw materials they need to grow. As a byproduct of photosynthesis, plants produce and release oxygen (O2). A. Photosynthesis and Light Intensity 1. In the Gizmo™, observe the aquatic plant. During photosynthesis, the plant produces oxygen, which is visible as bubbles leaving the plant. Set the Light intensity to 0%. (To quickly set a slider to a specific value, type the number in the field to the right of the slider and press Enter.) Check that the Temperature slider is set to 30.0°C and the CO2 level is set to 500ppm. Then select the BAR CHART tab. What is the rate of oxygen production? 0 M3 L1: Gizmo Simulation Lab: Photosynthesis - Honors Revised by NVLA: 10/15/2019 What does this tell you about the rate of photosynthesis when no light is present? Explain your answer. The rate of photosynthesis must be extremely slow since the lack of light intensity is causing no oxygen output. 2. Slowly drag the Light intensity slider up to 40%. What happens to the rate of oxygen production as the light intensity increases? The rate of oxygen production increases. What does this tell you about the rate of photosynthesis as the light intensity increases? As the light intensity increases the rate of photosynthesis increases. Does increasing light intensity always have the same effect on oxygen production? In other words, experiment with
