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 PowerPoint Lectures for Biology: Concepts & Connections, Sixth Edition Campbell, Reece, Taylor, Simon, and Dickey Lecture by Richard L. Myers Copyright © 2009 Pearson Education, Inc. Introduction: Plant Power Plants use water and atmospheric carbon dioxide to produce a simple sugar and liberate oxygen – Earth’s plants produce 160 billion metric tons of sugar each year through photosynthesis, a process that converts solar energy to chemical energy – Sugar is food for humans and for animals that we consume Copyright © 2009 Pearson Education, Inc. Introduction: Plant Power Scientists have suggested that plants can be used in ―energy plantations‖ to create a fuel source to replace fossil fuels – This would be an excellent energy solution, because air pollution, acid precipitation, and greenhouse gases could be significantly reduced Copyright © 2009 Pearson Education, .
