7. How many carbon atoms does glucose contain? (6) CO 2 (6) H 2 O (6) O 2 Glucose C ? H 12 O 6 1.1 2.4 3.6 4.12

8. Which reactant supplies all of the carbon used to make glucose in photosynthesis? (6) CO 2 (6) H 2 O (6) O 2 Glucose C 6 H 12 O 6 1.carbon dioxide 2.water 3.oxygen 4.sunlight

9. Photosynthesis is known as the “light reaction” because it is catalyzed by light. What is known as the “dark reaction” because it doesn’t need light? 1.carbon-oxygen cycle 2.chlorophyll regeneration 3.glucose storage 4.respiration

10. Photosynthesis and respiration both take place in the chloroplast. 1.True 2.False

11. Photosynthesis uses sunlight to create glucose (stored energy) from CO 2 and H 2 O. Why does a plant also perform respiration? 1.to create additional glucose without sunlight 2.to create a usable form of energy from a stored form of energy 3.to use glucose to create ATP 4.both 2 and 3

12. (6) CO 2 (6) O 2 Plants use photosynthesis to create stored energy in the form of glucose. Respiration releases this stored energy and uses it to form ATP. Which is an exothermic reaction?
