Learning Targets “I Can…” -Define “selective permeability.” -Model a living cell by using dialysis tubing in a liquid medium. - Predict the results of an experiment that involves animal cells rather than plant cells. Membrane Transport Lab The cell membrane is selectively permeable • What does it mean to be “selectively permeable”? Some molecules move easily through the membrane using diffusion, while other molecules cannot move through the membrane. Diffusion through a selectively permeable membrane . . . What you will do? • Add the following substances to a section of dialysis tubing . . . – Starch – Glucose – Albumin (egg white) – Oil This will represent the “cell.” What you will do? • Add the dialysis tubing to a beaker of iodine This will represent “outside the cell.” Data Elodea Cells Osmosis in Plant Cells Elodea Osmosis Elodea Osmosis Osmosis in Animal Cells Blood Cells Blood Cells Blood Cells References • • • • • • • • http://www.youtube.com/watch?v=IRQLRO3dIp8&NR=1 http://www.youtube.com/watch?v=wO1yq6YTJDI http://www.youtube.com/watch?v=VK-_YHakvho vcbio.science.ru.nl http://bcs.whfreeman.com/thelifewire/content/chp05/0502001.html josts.net discover.edventures.com library.thinkquest.org • science.pc.athabascau.ca • wn.com • biologylessons.sdsu.edu • csm.jmu.edu
