  2. Chlorophyll reflects this color of light. What is green? 5

  3. This is the role that chlorophyll plays in photosynthesis. What is to absorb light energy? 10

  4. This is what happens to electrons in a chlorophyll “a” molecule when they absorb light. What is they are excited to a higher energy level? 15

  5. This is what we call pigments other than chlorophyll. What are accessory pigments? 20

  6. This yellow pigment is found in plants but is not directly involved in photosynthesis. What is xanthrophyll? 25

  7. This is the location in the chloroplasts where the light reactions take place. What is the thylakoid membrane? 5

  8. These are the two products of the light reactions that provide energy for the Calvin cycle. What are ATP and NADPH? 10

  9. This is the source of the oxygen that is released during photosynthesis. What is water? 15

  10. The electrons lost by Photosystem 1 are replaced by electrons coming from here. What is Photosystem II? 20

  11. This process, that happens in the thylakoid membrane, is responsible for providing energy to produce ATP molecules. What is chemiosmosis. 25

  12. This is the location in the chloroplasts where the Calvin Cycle takes place. What is the stroma? 5

  13. In the Calvin Cycle, the carbon required to make organic molecules comes from this compound. What is carbon dioxide? 10

  14. In the Calvin Cycle, the hydrogen required to make organic molecules comes from this compound. What is NADPH? 15

  15. At the start of the Calvin Cycle, 3 molecules of carbon dioxide combine with this molecule to make 6 molecules of 3-PGA. What is RuBP? (RibuloseBiphosphate) 20

  16. One molecule of this compound is produced during the Calvin Cycle and used to make glucose or starch. What is G3P? (Glyceraldehyde 3-Phosphate) 25

  17. This technique is used to separate pigments based on their solubility in a solvent. What is chromatography? 5

  18. It is possible to demonstrate that photosynthesis is occurring by measuring the uptake of this molecule by a plant. What is carbon dioxide? 10

  19. In lab, we demonstrated that photosynthesis was occurring in geranium leaves by measuring the production of this molecule. What is starch? 15

  20. This pigment traveled the farthest on our chromatography strip. What is carotene? 20

  21. This is the color of phenol red in a very acidic solution. What is yellow? 25

  22. These are organisms that can make their own food. What are autotrophs? 5

  23. These are organisms that must eat food. What are heterotrophs? 10

  24. This is the equation for photosynthesis. What is 6CO2 + 6H20 C6H1206 + 602 15

  25. This is the plant organelle required for photosynthesis. What is the chloroplast? 20

  26. These are two types of organisms other than plants that can perform photosynthesis. What are some bacteria and some protists? 25
