ANALYSIS
4. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant? How do you
know?
1. Light Color
2. Light Level
3. C02 Level.
I know because this was shown throughout the experiment.
5. Write the equation for photosynthesis (use your book or online resources if you don't know it).
CHEMICAL PROCESS OF PHOTOSYNTHESIS:
2n c02 + 2nDH2 +Photons --------> Glucose.
6. What are the bubbles you are measuring in this lab? Why do the bubbles tell you how fast photosynthesis is
occurring?
We are measuring the bubbles of escaping oxygen being released from the plant. The bubbles tell us the speed of photosynthesis because they are a byproduct of photosynthesis.
7. Why is it important that you keep two variables constant (such as light level and color) while you're testing how
a third variable (CO2 Level) affects photosynthesis?
If you vary more than one variable, how will you know which is affecting the resulting data?
8. What settings can you put the simulator on to get the MAXIMUM rate of photosynthesis?
If you put color-less light, a c02 level of 10, and a light level of 10, then you can get up to 36 bubbles.
