Name :___________________
1. Light is really _energy____, which is used by plants during photosynthesis.
2. An __autotroph_____ makes its own food.
3. Specifically, photosynthesis occurs within the _chloroplast_____, which is an
organelle that only plant cells have.
4. White T-shirts reflect __all_______ colors of the visible spectrum.
5. Black T-shirts don’t reflect light they _absorb___ all the colors of the visible
spectrum
6. Please write the reactants and products for the photosynthesis equation.
____Light________
_CO2__ + ___H20__
→ _C6H12O6____ + __O2________
7. ADP is made into ATP by adding one __phosphate______.
8. Light with a short wavelength is ___high____ energy, while light with a long
wavelength is __short_____ energy.
Label the figure below:
9.Stroma
10. Thylakoid
11. Granum

13. If one P were removed from this molecule what would we call the new molecule?
____ADP_____________________.
Look at the figure to the right with the batteries
and flashlights.
14. What is this visual analogy trying to tell us about
ATP? __ADP is low energy and ATP is high
energy.________________________________

16. List three uses of ATP in cells/living things:
A.___Powers protein pumps_______
B.___Allows you to contract muscles__
C. __Powers making of proteins_____
17. Why do plants need pigments like chlorophyll?
______To capture light energy from the sun.
Complete the organizer below:
18_H20___
19__CO2___
20_O2___
21 C6H12O6__
22. In photosynthesis _Light___ energy is converted to
__chemical___ (glucose) energy.
23. What is the worst color light to shine on a plant in order to
make it grow? __Green_____. Why did you pick that color?
___Because green light is reflected by the chlorophyll in the plant
instead of absorbed – reflection of green light is why most plants
look green to our eyes.

photosynthesize.
A.
B.
C.
____Temperature____
____Light________
____Amount of Water___
