Jot down any extra tidbits of info 

2. 1. The wavelength of light determines its color
Part of the electromagnetic spectrum that we see is called “visible light”
Red, orange, yellow, green blue, violet
Plants absorb ____________ & _________
Blue/violet
Red

3. 2. Chemicals that absorb light are called pigments.

4. 3. Chlorophyll makes plants look green because it reflects green light

5. 4. Chloroplasts contain an abundance of saclike photosynthetic membranes called thylakoids

6. 5. The stroma is the fluid portion of the chloroplasts located outside the thylakoids

7. 6. The visible light absorbed by chlorophyll raises/increases the energy level of the chlorophyll’s electrons

8. 7.

9. 7.

10. 8.The hot potato represents two high-energy electrons
Think of a high-energy electron as being similar to a hot potato straight from the oven
Need an oven mitt (special carrier) to transport it
Similarly, a high-energy electron needs a special carrier molecule
NADPH carries them around cell

11. 9. A laundry basket represents the electron carrier and the laundry the high energy electrons

12. 10. Come from the chlorphyll molecules that have absorbed sunlight

13. 11. Carbon dioxide and water B
REACTANTS
PRODUCTS

14. 12. Oxygen and ATP (C)

15. 13. Stroma (A)

16. 14. LIGHT LIGHT DEPENDENT INDEPENDENT

17. 14.

18. 15. The chloroplasts work like solar cells
15. The chloroplasts work like solar cells. The chlorophyll absorbs the sun’s energy. This raises the energy levels of the electrons that are used for chemical reactions.
