Photosynthesis and Respiration

  1. ___________________________ is the process by which plants use sunlight as the energy source to make food.




    A. photosynthesis
  2. Photosynthesis is a three part process.

    True
    False
    False

    • It is a two part process that involves:
    • 1.) capturing the sun's energy
    • 2.) making sugars
  3. Which of the following is NOT part of the photosynthesis process:



    A. producing carbon dioxide
  4. What gas is USED in the photosynthesis process?




    A. carbon dioxide
  5. ________________ are the tiny openings in the underside of leaves through which carbon dioxide eneters the plant.




    D. stomata
  6. Which of the following is NOT required for photosynthesis.





    C. oxygen
  7. What two things are produced as a result of photosynthesis?




    B. oxygen and sugar
  8. This is the ___________ formula for photosynthesis.

    6CO2 + 6H20 >>>>> C6H12O6 + 6O2
    a. mathematical
    b. chemical
    c. nutritional
    d. algebraic
    b. chemical
  9. Some of the sugar produced in photosynthesis is stored for _______________.




    C. food
  10. A plant whic makes its own food is called a(n) ____________.




    B. autotroph
  11. A plant makes its own food.

    True
    False
    True.

    A plant is an autotroph, which means it makes its own food.
  12. Nearly all living things obtain energy either directly or indirectly from _________________ captured during photosynthesis.




    C. the energy of sunlight
  13. About 21% of the earth's atmosphere is nitrogen.

    True
    False
    False

    About 21% of the earth's atmosphere is OXYGEN.
  14. Almost all of the earth's oxygen is released into the atmosphere as a result of _______________.





    C. photosynthesis
  15. ________________ is the process by which cells break down simple food molecules such as glucose and release the energy they need.




    B. Cellular respiration
  16. What cell part is necessary to use stored sugars and oxygen to produce the energy needed for respiriation?




    C. mitochondria
  17. Photosynthesis and respiriation are ___________ processes.




    C. opposite
  18. Photosynthesis and respiriation keep the ___________ and _________ in the atmosphere fairly constant.




    D. oxygen / carbon dioxide
  19. Another form of releasing energy is ______________.




    A. fermentation
  20. What do yeasts break down during alcoholic fermentation to release energy?




    D. sugars
  21. The process that causes a build up of lactic acids in the muscle cells of an exercising human is called _____________.




    A. lactic acid fermentation
  22. Lactic acid builds up in the muscles causing them to feel weak, tired, and sore.

    True
    False
    True
  23. The following is the chemical formula for __________.


    C6H2O6 +6 O2 >>>>> 6CO2 + 6H2O + energy





    D. respiration
