NOTES FROM MR.ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute

Chapter 5 Notes The study of energy and its transformations is called thermodynamics. An aspect of thermodynamics that deals with the relationships between chemical reactions and energy changes involving heat is called thermochemistry. 5.1 The Nature of Energy Energy is defined as the capacity to do work or produce heat. Work is the energy used to cause an object with mass to move. Heat is the energy of an object that causes its temperature to increase. Kinetic and Potential Energy

Reflection: SS Chapters 6 & 7 I believe that there is much that we take for granted in our world today. One of these things we take for granted in the instant “treatment” for plants. We do so without even a second thought or consideration and continue to let it happen year after year. We also take for granted our everyday dependencies that stem from nature. I then question what it would take for us to realize our dependency on nature and to respect it as such. On page 73 of the reading‚ it discusses

AP Biology Name: Chapter 51 Guided Reading 1. How do behavioral ecologists define behavior? Behavioral ecologists define behavior as everything an animal does and how it does it 2. What is the focus of: a. Proximate questions of behavior? Focuses on the environmental stimuli‚ if any‚ that trigger a particular behavioral act‚ as well as the genetic‚ physiological‚ and anatomical mechanisms underlying it. b. Ultimate questions of behavior? Focuses on the evolutionary significance

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There
