Osmosis in Poisoned Plant Cells.
Tatina, Robert
American Biology Teacher, v60 n2 p144-47 Feb 1998
Describes two simple laboratory exercises that allow students to test hypotheses concerning the requirement of cell energy for osmosis. The first exercise involves osmotically-caused changes in the length of potato tubers and requires detailed quantitative observations. The second exercise involves osmotically-caused changes in turgor of Elodea species leaves. (PVD)
