1. What differences do you notice in the structures in the plants and their leaves of those living the rainforest compared to those in the desert?

2. Could these differences be adaptations? Explain. 

3. What are the major environmental differences that explain why plants in the desert are so different than plants in the rainforest?

4. Take a walk around your neighborhood, or your yard. Take a picture of a plant that you think has adaptations to exist in an arid environment. Upload this picture with your lab notebook. Explain in your notebook what evidence you used to decide this plant is likely adapted for an arid environment.

5. While on your walk, also take a picture of a plant that you think is better adapted for a rainforest type climate. Upload this picture with your lab notebook. Explain in your notebook what evidence you used to decide this plant is likely adapted for a wetter environment like the rainforest. 

PART D DISCUSSION 

In a discussion post, explain the carbon cycle and why it's imbalanced as if you were talking to someone in your family that is skeptical of this science. This should be at least 8-10 sentences. Some additional resources will be handy.  The link about how much hotter your hometown is now is interesting.

PART 8: TEST YOUR KNOWLEDGE 1. Based on everything you’ve learned from the animations, what is the overall purpose of photosynthesis?

2. Describe how oxygen gas (O2) is produced during photosynthesis. Include the specific structures in the plant where the reaction occurs.

3. Describe the path of an electron from a molecule of water to the sugar G3P.

4. Describe how ATP is produced in the light reactions.

5. Which of the following statements best explains how the energy in a photon of light is stored in a molecule of the sugar G3P? ________ a. Light energy directly provides energy to RuBP and CO2, which produce G3P in the Calvin cycle. b. Light energy directly provides energy to ATP synthase, which produces ATP during the light reactions. c. Light energy energizes electrons to make ATP and NADPH, which provide energy to produce G3P in the

Calvin cycle.

6. When three molecules of carbon dioxide (CO2) react with three molecules of RuBP during the Calvin cycle, six molecules of the sugar G3P are produced. One G3P molecule exits the Calvin cycle during Phase 2. What happens to the other five G3P molecules?
