4. III. Photosynthesis (Fig. 4-9)

5. What would slow down or even stop photosynthesis?

6. carbon dioxide + water + light energy
Photosynthesis
carbon dioxide + water + light energy
sugar + oxygen

7. III. Photosynthesis
A. Kinetic energy (light) is changed to potential energy (sugar). B. Special pigments, organelles, and enzymes must be present.

8. B. Special pigments
Chlorophyll is the primary pigment of photosynthesis
a) Green

9. 1. Chlorophyll c) located in chloroplasts
b)Used to power the process of photosynthesis
c) located in chloroplasts

10. B. Special organelles
2. Chloroplast a) discussed in Ch. 3

11. B. Special enzymes
3. Changing carbon dioxide and water into sugar requires several different enzymes.

12. III. Photosynthesis C. Sugar molecules 1. Stores potential energy
2. Form some of the structural parts of cells

13. Consumers obtain their energy by eating producers or other consumers.
