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

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

5. The stroma is the fluid portionof the chloroplasts located outside the thylakoids

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

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

9. A laundry basket represents the electron carrier and the

laundry the high energy electrons
