TAILIEUCHUNG - Lecture Biology (7th edition) - Chapter 10: Photosynthesis

Learning objectives of this chapter include: Describe the structure of a chloroplast; describe the relationship between an action spectrum and an absorption spectrum; trace the movement of electrons in linear, noncyclic electron flow; trace the movement of electrons in cyclic electron flow;. | Lecture Biology (7th edition) - Chapter 10: Photosynthesis Chapter 10 Photosynthesis PowerPoint Lectures for Biology, Seventh Edition Neil Campbell and Jane Reece Lectures by Chris Romero Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings • Overview: The Process That Feeds the Biosphere • Photosynthesis – Is the process that converts solar energy into chemical energy Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings • Plants and other autotrophs – Are the producers of the biosphere Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings • Plants are photoautotrophs – They use the energy of sunlight to make organic molecules from water and carbon dioxide Figure Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings • Photosynthesis – Occurs in plants, algae, certain other protists, and some prokaryotes These organisms use light energy to drive the synthesis of organic molecules from carbon dioxide and (in most cases) water. They feed not only themselves, but the entire living world. (a) On land, plants are the predominant producers of food. In aquatic environments, photosynthetic organisms include (b) multicellular algae, such as this kelp; (c) some unicellular protists, such as Euglena; (d) the prokaryotes called cyanobacteria; and (e) other photosynthetic prokaryotes, such as these purple sulfur bacteria, which produce sulfur (spherical (a) Plants globules) (c, d, e: LMs).
