    • mitochondria

       

  3. 00:01:08 

    Which of the following is not true about about chloroplast? 

    • the inside liquid part is the stroma

       

    • the individual disks inside the chloroplast are called thylakoids

       

    • a group of thylakoid disks are known as the grana

       

    • all of these are true

       

  4. 00:01:42 

    There are at least 4 different pigments that play a role in photosynthesis. 

    • true

       

    • false

       

  5. 00:02:15 

    Which color of light is the least important in photosynthesis 

    • blue

       

    • red

       

    • green

       

    • both A&B

       

  6. 00:02:44 

    Carbon dioxide enters the leaves of plants through a structure known as the stomata 

    • true

       

    • false

       

  7. 00:03:06 

    Which of the following is NOT essential for photosynthesis to occur? 

    • carbon dioxide

       

    • light

       

    • water

       

    • oxygen

       

  8. 00:03:40 

    Synthesis means to make or to put together 

    • true

       

    • false

       

  9. 00:03:57 

    The two main reactions of photosynthesis are the light and dark reactions(Calvin Cycle). 

    • true

       

    • false

       

  10. 00:04:14 

    Which of the following comes out of the the light reactions? 

    • ATP

       

    • NADPH

       

    • oxygen

       

    • All of these are correct

       

  11. 00:04:23 

    The big picture of what happens in the dark reactions or Calvin cycle is that carbon dioxide is used and glucose is produced 

    • true

       

    • false

       

  12. 00:04:38 

    The light reactions occur within the thylakoid membrane 

    • true

       

    • false

       

  13. 00:04:48 

    Two essential things that come into the light reactions are light and water 

    • true

       

    • false

       

  14. 00:05:34 

    What is responsible for moving electrons through the electron transport chain? 

    • ATP

       

    • light

       

    • NADPH

       

    • H+

       

  15. 00:05:56 

    When water is split apart in the light reactions oxygen is released along with H+ 

    • true

       

    • false

       

  16. 00:06:36 

    What is the result of electrons moving through the electron transport chain? 

    • H+ are moved from the stroma to inside the thylakoid

       

    • oxygen is released into the atmosphere

       

    • green light is reflected

       

    • ATP binds with NADPH

       

  17. 00:07:04 

    What two things are produced in the light reactions that go to the Calvin Cycle? 

    • ATP and ADP

       

    • NADPH and ATP

       

    • carbon dioxide and water

       

    • oxygen and glucose

       

  18. 00:07:17 

    How is ATP made during the light reactions? 

    • oxygen provides the necessary energy to convert ADP into ATP

       

    • H+ ions flow ATP synthase back out into the stroma and ATP is generated

       

    • the light causes the NADPH to move down its concentration gradient

       

    • all of these are true

       

  19. 00:07:56 

    What is the job of RuBisCo? 

    • Break apart ATP

       

    • remove H from NADPH

       

    • join CO2 to a 5 carbon compound

       

    • split apart a 6 carbon compound into two three carbon compounds

       

  20. 00:09:43 

    What takes place during photorespiration? 

    • not enough CO2 is available

       

    • oxygen jumps into the cycle in place of CO2

       

    • sugar is not made

       

    • all of these occur during photorespiration

       

  21. 00:10:42 

    Which of the following would not pass out of a stomata? 

    • ATP

       

    • CO2

       

    • H2O

       

    • O2

       

  22. 00:12:04 

    All plants have their stomata open 24 hours a day. This way they can get in as much carbon dioxide as possible in order to make glucose 

    • true

       

    • false
