Where are the Pigments, or light collecting units of photosynthesis found?
Thylakoid Membrane
Stroma
Chloroplast Membrane
Answer- a) Thylakoid Membrane

4. Question 2 Which of the following is an autotroph
A)Dog
B)Tree
C)Mushroom
D) Mr. Morales
Answer- B) Tree- Organisms that produce their own food are autotrophs

5. Question 3
Which of the following are used in the overall reactions for photosynthesis?
A) Carbon dioxide
B) Water
C) Light
D) All of the above
Answer- D) all of the above

6. Question 4
What does the Calvin cycle need from the light dependant reactions?
a) ATP
b) NADPH & ATP
c) NADP+
d) NADP+ & ATP
Answer- b) NADPH & ATP

7. Question 5
________ are stacked up on top of each other to compose granum
Answer- Thylakoids-

8. Question 6 Most plants appear green because chlorophyll
a) Does not absorb green light
b) Reflects violet light
c) Absorbs Green light
d) None of the above
Answer A) Does not absorb green light

9. Question 7 What are the green Structures in these plant cells
Answer- Chloroplasts

10. Question 8 What is the product of light-Dependent reactions?
Answer- ATP or Oxygen or NADPH

11. Question 9
If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production of energy sugars?
More sugars will be produced
No Sugars will be produced
Carbon Dioxide does not affect the production of high energy sugars in plants
Answer- B) No sugars will be produced (carbon dioxide needs to be fixed to produce sugar in the Calvin cycle)

12. Question 10
If you continue to increase the intensity of light that a plant receives, what happens?
The rate of photosynthesis increases with light intensity
The rate of photosynthesis decreases with light intensity
The rate of photosynthesis increases and then levels off.
The rate of photosynthesis does not change
Answer C) The rate of photosynthesis increases and then levels off (Too much light and the enzymes begin to denature and photosynthesis levels off)

13. Question 11 What effects photosynthetic rates?
Amount of carbon dioxide
Amount of light
Temperature
All of the above
Answer- D) All of the above

14. Question 12 Something that collects light is called a
a) Chloroplast
b) Pigment
c) Thylakoid
d) Grana
Answer- b) Pigment ( Pigments are the part of the thylakoid that collects the light)

15. Question 13 What is missing from the photosynthetic equation Answer
Water or 6H20

16. Question 14 The Calvin cycle is another name for
Light-independent reactions
Light-dependant reactions
Photosynthesis
Answer- A) Light-independent Reactions( Doesn’t depend on light)

17. Question 15
Energy release from converting ATP to ________ is commonly used for active transport, protein synthesis and muscle contraction
Answer- ADP

18. Question 16
This picture is depicting the Calvin Cycle, Study the picture and write what the product is.
Answer- C6H12O6

19. Question 17 The stroma is the space that surrounds
a)Thylakoids
b) Chloroplasts
c) Plant Cells
Answer- A) Thylakoids (Stroma is the fluid in the chloroplasts)

20. Question 18
What is the waste product of Photosynthesis
Answer- Oxygen

21. Question 19
Standard:Students know usable energy is captured from _________by chloroplasts and is stored through the synthesis of ___________ from carbon dioxide.
Answer- Sunlight, Sugar

22. Question 20 Last Question
________ is the carrier of electrons in a process called Electron Transport
Answer- NADPH

23. Summary
Photosynthesis is the action of converting light energy into chemical energy
Plants need Carbon dioxide, water and sunlight to make oxygen and sugar
Photosynthesis makes ATP from sunlight which is needed by the Calvin cycle to make SUGAR
