Photosynthesis
When plants harness the power of LIGHT to CREATE food!

3. Review from last week
Talk to your partner: What are vascular and non-vascular plants?

4. Essential Question: How do plants eat? Goal:
I can identify where photosynthesis takes place and write the chemical equation for photosynthesis.

5. Topic 1: Plants are Producers
Producers are organisms that make their own energy.
(They do not eat like us)

6. Discuss with table partner
Why do plants need energy? What do they use it for?

7. Topic 1: Plants are Producers
Plants do a process called photosynthesis, which is when they use energy from the sun to change carbon dioxide and water into sugar and oxygen.
Plants eat sugar that they make inside their bodies!

8. Topic 2: Photosynthesis Equation

9. Topic 2: Photosynthesis Equation
In photosynthesis plants uptake certain substance and change them
(we can remember this by putting it into an equation)

10. Topic 2: Photosynthesis Equation
1 cup flour + 1 cup milk + 2 TBSP baking powder + 1 egg + 1 TSP salt
(REACTANTS)
(heat)
> 12 Pancakes
(PRODUCTS)

11. Topic 2: Photosynthesis Equation
light energy
6 CO2 + 6 H2O > C6H12O6 + 6 O2
How to read that:
Carbon dioxide + water + light YIELDS Glucose + oxygen
Reactants Products

12. Topic 2: Photosynthesis Equation

13. Topic 2: Photosynthesis equation
Oxygen is a product of photosynthesis
We wouldn’t be able to breathe without plants!!!

14. Get up and find someone new
Partner A: list all of the reactants in the photosynthesis (the starting ingredients)
Partner B: list the products in the photosynthesis (what comes out of it). Why are these products important for humans?

15. Sketch it!

16. Topic 3: Where??!!

17. Topic 3: Where? Carbon dioxide enters tiny holes = stomata
Sunlight is absorbed
Water from roots

18. Stomata close up

19. Chloroplasts absorb sunlight

20. Topic 3: Where?
Photosynthesis takes place in the chloroplasts (the green parts)

21. Get up and find someone new (take your notes)
What is a stomata?
How do plants get the reactants they need to do photosynthesis?

22. Quiz Yourself!
Use your notes from today to answer the following questions

23. Where do plants get food?
Soil
They eat prey
They make it themselves
They take nutrients from water

24. Water and carbon dioxide are converted into sugar and oxygen through the process of….
Glycolysis
Photosynthesis
Cellular Respiration
Fermentation

25. Which of the following is an example of a producer?
Dog
Cat
Elephant
Tree

26. The TWO parts of a chemical equation are…
Reactants and Products
Oxygen and Carbon dioxide
Mitochondria and chloroplasts
Peanut butter and jelly

27. Write out the CORRECT chemical equation for photosynthesis

28. 6 CO2 + 6 H2O ------------> C6H12O6 + 6 O2
Check Yo Self…
6 CO2 + 6 H2O > C6H12O6 + 6 O2

29. In which organelle does photosynthesis take place?
Mitochondria
Golgi body
Nucleus
Chloroplast

30. Pat yourself on the back!
Now you can….
Identify where photosynthesis takes place
Write the chemical equation for photosynthesis
Explain why we need photosynthesis
Pat yourself on the back!

31. Essential Question
What is the difference between the Light Reaction and Calvin Cycle during photosynthesis?
Objective:
I can explain how glucose is made.

32. Let’s Review!
Using the notecards at your table, rearrange them into the correct chemical equation for photosynthesis.

33. Does it look like this?
6 CO2 + 6 H2O > C6H12O6 + 6 O2

34. 2 Cycles
There are two cycles that work together to create glucose (C6H12O6)
Light Reactions (require light)
Calvin Cycle (doesn’t require light or dark)
Photolysis- when a chemical (like water) is broken down by photons

35. Light Reaction- Needs Light
Occurs in the grana of chloroplasts
Adds a phosphate to ADP to become ATP
Splits water (H2O) to release O2 (oxygen) and H+ (hydrogen)
Sends H+ over to Calvin Cycle
That’s what we breathe!!

36. That pore is called a stomata
Remember Diffusion?
After the Light Reaction, oxygen (O2) diffuses out of the cell that we then breathe!
That pore is called a stomata

37. Calvin Cycle- Doesn’t need light!
Occurs in the stroma of chloroplasts
Takes in CO2 (Carbon Dioxide)
Uses the ATP (energy) and H+ from Light Reaction
Synthesizes (makes) GLUCOSE (C6H12O6)
This can happen day or night
