Unit 3: The Life of a Cell   Chapter 9: Energy in a Cell   p. 226 MIT Biology HyperTextbook This site provides detailed information about the reactions in photosynthesis. Follow the link to learn more about this process. What are the two primary pigments involved in photosynthesis? What organisms derive reductive power by oxidizing compounds such as hydrogen gas, ammonia, or iron? What is this energy production system called? p. 246 POL Home Page This Web site is maintained by the American Society for Photobiology, a Washington, D.C. group that supports photobiological research. How is photobiology different from other disciplines in biology? Photosynthesis Center Everything you wanted to know about photosynthesis. At the bottom of the page is a link that describes science fair projects related to photosynthesis. Choose one of these experiments and conduct it for the science fair. Photosynthetic Pigments Visit this site for a breakdown of plant pigments. What is the difference between chlorophylls and carotenoids? Plant Pigment Activity This is a lab procedure that you can perform with the pigments in spinach leaves. With your teacher's supervision, perform this experiment and compare the results with others in your class. p. 236 American Society for Biochemistry and Molecular Biology The ASBMB is a nonprofit scientific and educational organization for professional biochemists. After visiting this page, write a journal article pretending you are a biochemist, explaining how you use the site in your profession. Cellular Respiration Check out this site for a detailed look at cellular respiration including the citric acid cycle. How many ATP molecules are formed during cellular respiration? p. 142 Unit 3: The Life of a Cell Hydrogen Bonding in Organic and Biochemistry Access this site to learn how hydrogen bonding occurs and its importance in biology. What kind of forces are at work in a hydrogen bond? Create a poster by drawing diagrams of the different biochemical models. Virtual Cell Follow the link to this site to take a 3-D navigational tour through a plant cell. What structure is unique to plant cells? View an electron micrograph of a real plant cell and compare it to the virtual cell in a journal article. The Cell Nucleus I Visit this site to focus on the cell nucleus. Use this information to make a 3-D model of a human cell. The Cell This site covers cells in detail. Visit it to learn about the different types of cells and their purpose. Visit the Cell Gallery and write a journal entry describing the properties of three different types of cells.
