1. Photosynthesis
And
Cellular Respiration

2. Energy and Life Energy is the capacity to do work
All living things require energy
Cell “work” that requires energy to
Grow
Reproduce
Transport
Move

3. Photosynthesis
Photosynthesis: The process that plants and some single-celled organisms use to make glucose (sugar).
Photosynthesis occurs in the Chloroplast
Takes in CO2 and H2O from the environment
Converts sunlight energy into chemical energy in the bonds of glucose

4. Draw Photosynthesis

5. Chemical Equation for Photosynthesis
Energy from the sun
Carbon Dioxide + Water = Glucose + Oxygen
___CO2 + ___H2O  C6H12O6 + ___O2 6 6 6

6. Chemical Equation for Photosynthesis
Energy + Carbon Dioxide + Water = Glucose + Oxygen
(From the sun)
Products
Reactants

7. Glucose produced by photosynthesis can then be…
Used for energy in cellular respiration
Glucose is like the plant’s food.
It is converted to starch and stored in the plant.

8. Cellular Respiration
Cellular Respiration – the process where the energy stored in the chemical bonds of glucose is converted to energy (ATP).
2 Types:
Aerobic (with oxygen)
Anaerobic (without oxygen/fermentation)

9. What is ATP?
ATP: Adenosine Triphosphate.
Energy source in the cell

10. Where does cellular respiration occur inside the cell?

11. The Mitochondria “The Powerhouse of the Cell” “The Mighty Mitochondria”

12. Chemical Equation for Cellular Respiration
Glucose + Oxygen = Carbon Dioxide + Water + Energy 6 6
C6H12O6 + ___O2  ___CO2 + ___H2O + ____ATP 6
36-38

13. Chemical Equation for Cellular Respiration
Glucose + Oxygen = Carbon Dioxide + Water + Energy

14. Card Sort Activity
Go to your lab station and sort the cards into the correct equations for Photosynthesis and Cellular Respiration.
You may NOT use your notes! Discuss with your group and make your best guess if you are unsure.
Raise your hand when finished and I will check them.
If your group gets both equations correct on the first try, then you get Bonus Bucks!

15. Compare the Equations After the card sort, look back at the equations.
What did you notice about the Chemical Equations for Photosynthesis and Cellular Respiration?

16. Compare the Equations After the card sort, look back at the equations.
What did you notice about the Chemical Equations for Photosynthesis and Cellular Respiration?
The equations are the
inverse of each other!
