| 10. The energy conversion that occurs during photosynthesis is _______ to _____________. | radiant or solar to chemical
🗑
|
||||
| 11.The products of photosynthesis are _________ and ________. | glucose and oxygen
🗑
|
||||
| 12. In the diagram below, structure A is the ______ and is site of _______________. | mitochondria cellular respiration
🗑
|

| 13. The chemical equation, 6O2 + C6H12O6 6H2O + 6CO2, represents the cell process _________________. The reactants are ____________ and _____________. The products are ____________ and ___________. | cellular respiration
oxygen and glucose (sugar)
carbon dioxide and water
🗑
|
||||
| 14. Water evaporating from the plant’s leaves during photosynthesis is called __________. | transpiration
🗑
|
||||
| 15. The energy releasing process that requires no oxygen is called, _________ _____________ ___________________ . It takes place in the muscle cells of a runner …feel the burn. This process does NOT occur in which type of cells? ______________ | lactic acid fermentation
plant cells
🗑
|
||||
| 16. Cellular respiration and photosynthesis are _________ reactions or equations. | opposite
🗑
|
||||
| 17. Where is the energy coming from in the following equation? _____ What would happen if it was not present? _____ | sunlight the reaction would not occur
🗑
|
||||
| 18. Diagram how energy is transferred in the processes of photosynthesis and cellular respiration: | Radiant (solar) (light) energy is transferred into chemical energy then into mechanical energy (the energy of motion).
🗑
|
||||
| 19.Why is cellular respiration essential to life? ________________________________________________ | Cellular respiration releases energy for the cell to use to function
🗑
|
||||
| 20. What is the structure shown? ___________________ What cell process occurs there? _____________ | chloroplast
photosynthesis
🗑
|
||||
| 21. What kind of organisms undergo photosynthesis? _____________________ | autotrophs or producers
🗑
|
||||
| 22. What kind of organisms undergo cellular respiration? _______________________________ | autotrophs or producers and heterotrophs or consumers
🗑
|
||||
| 23. Explain photosynthesis. | Photosynthesis involves capturing the energy in sunlight and using that energy, carbon dioxide and water to produce glucose (sugar) and release oxygen.
🗑
|
||||
| 24. How are photosynthesis and cellular respiration opposite reactions? | During photosynthesis, plants use carbon dioxide and water to produce sugars and oxygen. During cellular respiration, oxygen combines with glucose to produce water and carbon dioxide
🗑
|
||||
| 25. How do animals get energy when they cannot make their own food? | Animals depend indirectly on the sun’s energy. Plants use energy from the sun to produce sugars. Because animals cannot do this, they eat plants or animals that eat plants. Without plants, animals could not survive.
