The main contents of this chapter include all of the following: An overview of photosynthesis, the light reactions: converting solar energy to chemical energy, the calvin cycle: converting CO2 to sugars, photosynthesis reviewed and extended. | Chapter 7 Photosynthesis: Using Light to Make Food 0 Introduction Plants, algae, and certain prokaryotes convert light energy to chemical energy and store the chemical energy in sugar, made from carbon dioxide and water. © 2012 Pearson Education, Inc.

Autotrophs are the producers of the biosphere Photoautotrophs use the energy of light to produce organic molecules. Chemoautotrophs are prokaryotes that use inorganic chemicals as their energy source. Heterotrophs are consumers that feed on plants or animals, or decompose organic material. © 2012 Pearson Education, Inc.

Figure Figure Photoautotroph diversity Photosynthesis occurs in chloroplasts in plant cells Chloroplasts are the major sites of photosynthesis in green plants. Chlorophyll is an important light-absorbing pigment in chloroplasts, is responsible for the green color of plants, and plays a central role in converting solar energy to chemical energy. © 2012 Pearson Education, Inc.
