Water and Life Chapter 3 Overview: The Molecule That Supports All of Life Water is the biological medium on Earth All living organisms require water more than any other substance Most cells are surrounded by water, and cells themselves are about 70?95% water The abundance of water is the main reason the Earth is habitable ? 2011 Pearson Education, Inc. Figure 3.1 Polar covalent bonds in water molecules result in hydrogen bonding The water molecule is a polar molecule: the opposite ends have opposite charges Polarity allows water molecules to form hydrogen bonds with each other ? 2011 Pearson Education, Inc. Figure 3.2 Hydrogen bond Polar covalent bonds ? ? ? + ? + ? ? ? ? ? + ? + ? ? Four emergent properties of water contribute to Earth?s suitability for life

AP Biology Reading Guide Chapter 3: Water and the Fitness of the Environment Fred and Theresa Holtzclaw Copyright ? 2010 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 3: Water and the Fitness of the Environment Concept 3.1 The polarity of water molecules results in hydrogen bonding 1. Study the water molecules at the right. On the central molecule, label oxygen (O) and hydrogen (H). 2. What is a polar molecule? Why is water considered polar? 3. Now, add + and ? signs to indicate the charged regions of each molecule. Then, indicate the hydrogen bonds. 4. Explain hydrogen bonding. How many hydrogen bonds can a single water molecule form?

Name Period Chapter 3: Water and Life Concept 3.1 Polar covalent bonds in water result in hydrogen bonding Study the water molecules at the right. On the central molecule, label oxygen (O) and hydrogen (H). What is a polar molecule? Why is water considered polar? Now, add + and - signs to indicate the charged regions of each molecule. Then, indicate the hydrogen bonds. Explain hydrogen bonding. How many hydrogen bonds can a single water molecule form? Concept 3.2 Four emergent properties of water contribute to Earth?s suitability for life Hydrogen bonding accounts for the unique properties of water. Let?s look at several. Cohesion, Adhesion, and Surface Tension Distinguish between cohesion and adhesion.

CHAPTER 3 ? WATER AND LIFE THE MOLECUES THAT SUPPORT ALL OF LIFE Water is the only natural substance to exist in all 3 states of matter: Solid Liquid Gas WATER molecule is a polar molecule It has a positive and a negative end It can make up to 4 Hydrogen bonds that break and reform instantaneously. 4 Emergent properties of water COHESION The linking together of like molecules, often by hydrogen bonds. Water sticks to itself Adhesion- water sticks to something else Surface Tension ? A measure of how difficult it is to stretch or break the surface of a liquid. Water has a high surface tension because of the hydrogen bonding of surface molecules MODERATION OF TEMPERATURE BY WATER HEAT AND TEMPERATURE Kinetic Energy ?
