15. Where is the Palisade layer found?
16. Is the Palasade layer on the top or bottom of the leaf? Why?
17. What are the “trap doors” called in the bottom of the leaf? Why are these structures found primarily on the bottom of the leaf?
18. What do these trap-door structures let in in/out?
19. What dilemma do plants face that live in hot dry climates?
20. What are the inputs to the light reaction?
21. What are the products of the light reaction?
22. The oxygen produced in the light reaction comes from where? How do scientists know this?
23. What are the steps for the light reaction?
a. Where do the electrons come from?
b. What is the splitting of water with light called?
c. What else do we get from the water splitting?
d. What happens at the reaction center?
e. What is the light absorbing pigment called in the reaction center?
f. What does the string represent?
g. What are the proteins embedded in the ETC called?
h. What does the Electron Transport Chain do?
a. What causes the electrochemical gradient of hydrogen ions (protons) across the thykaloid membrane?
b. What powers the production of ATP?
c. What enzyme makes ATP.
d. What happens at the reaction center in Photosystem I?
e. Where does the electron go then?
f. Where do the electrons finally end up in the light reaction?
g. Where does ATP & NADPH go?
24. Using your model show both the non- cyclic and cyclic light reaction pathway of electron flow. Explain their differences. (think about what they produce).
25. Why is the cyclic light reaction pathway necessary?
26. What are the products of each of the above pathways?
27. What are the inputs into the Calvin cycle?
28. What are the general products of the Calvin cycle?
29. What specific molecule does the Calvin Cycle produce?
30. Where does the Calvin cycle take place in the chloroplast?
31. What is rubisco? What is its function?
32. What powers the production of carbohydrates from carbon dioxide in the Calvin cycle?
33. What is the overall equation for photosynthesis?
34. Why do leaves change color in the fall?
35. What did Engelmann’s experiment show? What evidence supported this conclusion?
36. Be able to describe in detail each step of your 3-D Model?
37. What are some of the similarities between cellular respiration and photosynthesis?
38. What are some of the differences between cellular respiration and photosynthesis?
39. When and where is p-synthesis thought to have occurred in the evolutionary stages of life on Earth?
40. What is thought to be the ecological consequences of photosynthesizing organisms early in the history of life?
41. How does the structure and function relationship in the chloroplast allow cells to capture the energy available in sunlight and convert it to chemical bond energy via photosynthesis?
42. Relate the following statement to pigments: “Variations within molecular classes provide cells and organisms with a wider range of functions”.
43. Be able to compare and contrast CAM plants to C4 plants (hint: one is a spatial solution one is a temporal solution). What environmental conditions are CAM and C4 plants better adapted to than C3 plants?
44. Explain the process of photorespiration in plants.
45. Be ready sing the photosynthesis rap word for word to your fellow carbon units:)
