1. DO NOW Please re-write in scientific notation 4,323,232?
What are the five (5) standard parts of a formal lab report?
What is the difference between autotrophs and heterotrophs? Give an example of each.
Draw and label ATP.

2. Chlorophyll and Chloroplasts

3. What is the closest star to the Earth?
Why is that star so important to life?

4. Light Energy
WHAT ?!?

5. Light Spectrum

6. Chlorophyll is a Pigment
What color is chlorophyll?
What color(s) are absorbed?
What color(s) are reflected?
Why?

7. Chloroplasts

8. Chloroplasts: Where Photosynthesis Happens.
Thylakoids: Flat bag shaped membranes, arranged in stacks.
Stroma: liquid filled space around the thylakoid.

9. High Energy Electrons
NADP+ : A molecule that accepts electrons from chlorophyll and carries them to places where sugars are built.

10. DO NOW What is NADP+ (describe)? How are thylakoids arranged?
What are the products of photosynthesis?
Where does photosynthesis take place?

11. The Equation
6 CO2 + 6 H2O light C6H12O6 + 6 O2
Products?
Reactants?

12. Light Dependent & Independent

13. Light-Dependent Reactions
A reaction of photosynthesis that uses light energy to make ATP and NADPH
Light-Independent Reactions
A reaction of photosynthesis that uses ATP, NADPH and CO2 to make sugars

14. Light-Dependent Reactions
Photosystems: baglike membranes holding chlorophyll and proteins. They take in light and use it to add energy to electrons.

15. Photosystem II comes first ?!?
Photosystem II: absorb light and release high energy electrons. They get passed down the electron transport chain a group of carrier proteins that pump positive ions inside the thylakoid.

16. Photosystem I comes second ?!?
Photosystem I: absorb light and release high energy electrons. They get passed down another electron transport chain used to make NADPH

17. Light-Independent Systems – Calvin Cycle
Calvin cycle: creates high energy sugars from ATP and NADPH

18. Light-Independent Systems – Calvin Cycle
Reactants? Products? Where does the energy come from first? Can this occur at night?

19. Factors Affecting Photosynthesis
What factors will affect photosynthesis?
Why?

20. Factors Affecting Photosynthesis
Light - How?
Temperature - How?
Water - How?

21. C4 Plants and CAM Plants
C4 Plants – Allows CO2 into the Calvin cycle even when there isn't much available. Corn and Cane Sugar are examples.

22. C4 Plants and CAM Plants
CAM Plants – Save water by taking air into leaves only at night. Examples are Pineapple bushes and Cacti.
