Lecture Campbell biology: Concepts and connections (Seventh edition) - Chapter 7: Photosynthesis: Using light to make food

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. Introduction Algae farms can be used to produce oils for biodiesel or carbohydrates to generate ethanol. © 2012 Pearson Education, Inc.

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. 7.1 Autotrophs are the producers of the biosphere Photosynthesis in plants takes place in chloroplasts, converts carbon dioxide and water into organic molecules, and releases oxygen. © 2012 Pearson Education, Inc.

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. 7.2 Photosynthesis occurs in chloroplasts in plant cells Chloroplasts are concentrated .
