Review Questions (photosynthesis and respiration) – For Transport Questions – look at your quiz study guide!!!
1. What gives plants the energy they need to complete photosynthesis?
ATP WHICH THEY MAKE IN THEIR MITOCHONDRIA
2. Which organelle captures the energy from the sun and uses it to undergo photosynthesis? CHLOROPLAST
3. What is the objective of photosynthesis? (Why does it take place?) TO MAKE STORED ENERGY (FOOD ) FOR THE
PLANT
4. Write the equation for photosynthesis (CO2WS  GO). Make sure you memorize it.
6CO2 + 6H20 + SUNLIGHT → C6H12O6 + 6O2
5. How does your body get the energy it needs from the food you eat and the oxygen you breathe (what process
allows cellular energy to be made)?
CELLULAR RESPIRATION
6. Where does cellular respiration take place (organelle)?
MITOCHONDRIA
7. Write the equation for cellular respiration. Make sure you memorize it (GO  CO2W And Take Prisoners!).
C6H12O6 + 6O2→ 6CO2 + 6H20 + ATP
8. How do the processes of photosynthesis and cellular respiration relate to each other? Explain in terms of
products and reactants and in terms of light energy, stored chemical energy, and usable chemical energy.
THE PRODUCTS OF PHOTOSYNTHESIS ARE THE REACTANTS OF CELLULAR RESPIRATION AND THE PRODUCTS OF
CELLULAR RESPIRATION ARE THE REACTANTS OF PHOTOSYNTHESIS. PHOTOSYNTHESIS BEGINS WITH LIGHT ENERGY
THAT IS CHANGED TO STORED CHEMICAL ENERGY IN THE CHLOROPLAST. STORED CHEMCIAL ENERGY IS CHANGED TO
USEABLE CHEMICAL ENERGY (ATP) IN THE MITOCHONDRIA DURING CELLULAR RESPIRATION.
9. What does breathing have to do with cellular respiration?
THE OXYGEN WE BREATHE IN IS USED IN CELLULAR RESPIRATION TO CREATE ATP.
10. Compare and contrast photosynthesis and cellular respiration (use the words: plants, animals, mitochondria,
chloroplast, energy, products, reactants)
PHOTOSYNTHESIS OCCURS IN PLANTS ONLY AND USES THE FOLLOWING REACTANTS: SUN’S ENERGY, CARBON DIOXIDE
AND WATER, TO CREATE THE FOLLOWING PRODUCTS: GLUCOSE AND OXYGEN. THIS OCCURS IN THE CHLOROPLAST.
GLUCOSE AND OXYGEN FROM THE PLANT’S CHLOROPLAST IS COMBINED WITH OXYGEN TO COMPLETE CELLULAR
RESPIRATION WHICH OCCURS IN THE MITOCHONDRIA OF PLANTS AND ANIMALS.
11. In which cell would you expect to find the greatest number of mitochondria – in active cells or non-active cells?
Why?
WE WOULD EXPECT TO FIND MORE MITOCHONDRIA IN ACTIVE CELLS BECAUSE THEY WOULD NEED MORE ENERGY.
12. Explain how energy gets transferred from the sun to usable chemical energy (ATP) in the cell. Use the words:
radiant (light) energy, stored chemical energy, useable chemical energy, photosynthesis, respiration, glucose,
and ATP in your answer!
DURING PHOTOSYNTHESIS, THE CHLOROPLAST USES RADIANT OR LIGHT ENERGY TO BREAK THE BONDS OF
WATER AND CARBON DIOXIDE. THESE ATOMS ARE REARRANGED TO BECOME GLUCOSE AND OXYGEN.
GLUCOSE IS STORED CHEMICAL ENERGY. IN THE MITOCHONDRIA, GLUCOSE (STORED CHEMICAL ENERGY) IS
CHANGED INTO CARBON DIOXIDE, WATER, AND ATP (USEABLE CHEMICAL ENERGY) DURING CELLULAR
RESPIRATION.
