Name______________________________________
1. Record the overall reaction for photosynthesis and then cellular respiration.
2. How do the two compare?
3. Describe (in detail) where photosynthesis takes place.
4. Name three plant pigments that are involved in photosynthesis?
5. Why do leaves appears green to us? Us different wavelengths of light in your explanation.
6. Look at a picture of the electromagnetic spectrum. The amount of energy changes based on the
wavelength. If wave length increases what happens to the amount of energy? What about violet light?
7. Name and give a short description, in your own words, for the two stages of photosynthesis.
8. What happens to H2O during the 1st stage?
9. What molecule is given off during the light reactions? Is this a product or a reactant?
10. What two energy molecules are products of the light reactions and reactants in the Calvin cycle?
11. What happens to CO2 molecules in the 2nd stage?
12. What molecule do plants make in order to store the product of glucose?
13. This diagram shows both stages of photosynthesis. Label and study!
