Introduction: In this simulation, you will be looking at the production of carbon dioxide as a plant photosynthesizes. Oxygen is measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis.

PreLab Questions
Q: To survive, what gas do we need to breathe in? __________________________________
Q: Where is this gas produced? _______________________________ A byproduct of photosynthesis in oxygen gas. Plant use some of the oxygen that they produce, but most of it is released through small holes in their leaves. You will monitor the rate of photosynthesis in …show more content…
Make sure to include information such as the color of light, light intensity, level of CO and the amount of bubbles produced. (Use the previous
2 experiments as a guide)

PostLab ANALYSIS
1. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant?
2. Write the equation for photosynthesis (use your book or online resources if you don’t know it).
3. What are the bubbles you are measuring in this lab? Why do the bubbles tell you how fast photosynthesis is occurring?
4. Why is it important that you keep two variables constant (such as light level and color) while you’re testing how a third variable (CO Level) affects photosynthesis?

5. What settings can you put the simulator on to get the MAXIMUM rate of photosynthesis? 6.Why would it be hard to find the ideal CO level if the light intensity was set too low?
