Lecture Campbell biology: Concepts and connections (Seventh edition) - Chapter 2: The chemical basis of life. In this chapter we will discuss: Elements, atoms, and compounds; chemical bonds; water's life supporting properties. | Chapter 2 The Chemical Basis of Life 0 Figure Chapter 2: Big Ideas Elements, Atoms, and Compounds Chemical Bonds Water’s Life- Supporting Properties Introduction Chemicals are the stuff that make up our bodies, the bodies of other organisms, and the physical environment. © 2012 Pearson Education, Inc. Introduction Life’s chemistry is tied to water. Life first evolved in water. All living organisms require water. The chemical reactions of your body occur in cells consisting of 70–95% water. © 2012 Pearson Education, Inc. ELEMENTS, ATOMS, AND COMPOUNDS © 2012 Pearson Education, Inc. Living organisms are composed of matter, which is anything that occupies space and has mass (weight). Matter is composed of chemical elements. An element is a substance that cannot be broken down to other substances. There are 92 elements in nature—only a few exist in a pure state. Organisms are composed of elements, in combinations called compounds © 2012 Pearson Education, .
