Ch.7 Notes and Lecture Date Notes Questions 10/7/15 Unless something there is something non soluble only a helper protein can help it get through Phospholipid Bilayer Endocytosis is when a cell membrane can take/release atoms. Fatty acid tails will not associate with ions Diffusion when high concentration to low concentration Active Transport Learn proteins on the membrane Proteins make membrane selectively permeable 10/8/15 Passive transport, know all forms Diffusion as well Water can pass directly though phospholipid membrane Pores allow passage for chemicals to enter the cell. Diagram, #1 Facilitated diffusion: Use of proteins on the membrane to take in and put out chemicals. Osmosis: diffusion of water through selectively permeable barrier. Diagram 2

Agar Cell Diffusion Vanderbilt Student Volunteers for Science Summer, 2005 Training Presentation Important!!! Please use this resource to reinforce your understanding of the lesson! Make sure you have read and understand the entire lesson prior to picking up the kit! We recommend that you work through the kit with your team prior to going into the classroom. This presentation does not contain the entire lesson?only selected experiments that may be difficult to visualize and/or understand. I. Introduction (p.2) What is a cell? Cells are the structural and functional unit of all living organisms. How do cells grow? Most cells grow, but upon reaching a certain size, a cell will divide becoming two smaller cells. How do cells take in nutrients and get rid of wastes?

INTRODUCTION TO HUMAN GEOGRAPHY Chapter 1 What Is Human Geography? The study of How people make places How we organize space and society How we interact with each other in places and across space How we make sense of others and ourselves in our locality, region, and world Globalization A set of processes that are: increasing interactions deepening relationships heightening interdependence without regard to country borders. A set of outcomes that are: unevenly distributed varying across scales differently manifested throughout the world. What Are Geographic Questions? The spatial arrangement of places and phenomena (human and physical) How are things organized on Earth? How do they appear on the landscape? Where? Why? So what?

Key Issues Where are folk and popular leisure activities distributed? Where are folk and population material culture distributed? Why is access to folk and popular culture unequal? Why do folk and popular culture face sustainability challenges? Learning Outcomes 4.1.1: Compare the origin, diffusion, and distribution of folk and popular culture. 4.1.2: Compare the characteristics of folk and popular music. 4.1.3: Describe how sports have been transformed from folk to popular culture. 4.2.1: Compare reasons for distribution of clothing styles and folk and popular culture. 4.2.2: Understand reasons for folk food preferences and taboos. Learning Outcomes 4.2.3: Describe regional variations in popular food preferences.

Properties of water

Water Potential (?) Water potential (?) is a measure of water?s potential to do work. In order to do work, an object must be able to apply enough force to another object to cause displacement. In order for water to displace another object, water must be moving. The largest water potential any volume of water can have, if only standard atmospheric pressure is being applied to that volume of water, is defined as 0. This is the water potential for distilled water. Distilled water has the greatest potential to move, and thus displace another object.

Practice Problems ? Osmosis and Water potential Use this key to answer all the problems below. If you choose B or C, rewrite the statement so that it is complete and true. A = TRUE B = FALSE C = NOT ENOUGH INFORMATION PROBLEM ONE: The initial molar concentration of the cytoplasm inside a cell is 2M and the cell is placed in a solution with a concentration of 2.5M. Initially, free energy is greater inside the cell than outside It is possible that this cell is already in equilibrium with its surroundings. Initially, solute concentration is greater outside the cell than inside. Water will enter the cell because solute potential is lower inside the cell than outside.
