REFER to MODEL 1 a- In what cell organelle does photosynthesis occur? _______________________________ b- What are 3 reactants needed for photosynthesis? 1) ____________________ 2) ____________________ 3) ____________________ c- What are 2 products of photosynthesis? 1) ____________________ 2) ____________________ 2. REFER to MODEL 1 a- In what cell organelle does cellular respiration occur? _______________________________ b- What are 2 reactants needed for cellular respiration? 1) ____________________ 2) ____________________ c- What are 3 products of cellular respiration? 1) ____________________ 2) ____________________ 3) ____________________ 3. What 4 substances are recycled during P and CR? 1) __________________ 2) __________________ 3) __________________ 4) __________________ 4. What is the one component that is not recycled in P and must be constantly available? ____________________ 5. Are chloroplasts found in most plant cells? EXPLAIN: yes no 6. Are mitochondria found in most plant cells? EXPLAIN: 7. Are chloroplasts found in animal cells? EXPLAIN: 8. Are mitochondria found in animal cells? EXPLAIN: yes no yes no yes no 9. Write a complete sentence explaining the relationship between the reactants and products of P and CR: 10. CONSIDER/DISCUSS: “Plants can survive on their own because they make their own food. Animals cannot survive on their own but need plants for their survival.” As a group, come to an agreement about this statement and defend your stand. 11. As a group, make a quick list of some foods you ate yesterday. HYPOTHESIZE what would happen to the supply of these foods if the sun’s energy was no longer available. 12. EXPLAIN how the energy of an athlete used during a football game came from the energy of sunlight. 13. REFER to MODEL 2 DRAW a green star by each process that represents P / a red star by each process that represents CR [A/B/C/D] 14. WRITE/LABEL equations for P & CR: P: ___________________________________________________________ CR: ___________________________________________________________ [CIRCLE the carbon dioxide in each equation] 15. When matter from plants and animals decay [rot], microorganisms responsible for the decomposition process respire. With this information in mind, do you need to add any red stars to MODEL 2? _____ ADD stars if needed. EXPLAIN: 16. LIST any chemical processes other than P & CR that are taking place in MODEL 2: 17. Are any of these processes due to human activity? ______ EXPLAIN: 18. What generalizations can you make about the balance of carbon dioxide in MODEL 2 over a long period of time? 19. How would the burning of fossil fuels upset the balance of the carbon cycle? 20. EXPLAIN how deforestation, the burning and cutting down of trees, affects the carbon cycle.
