Osmosis of Potato Strips : Grin Verlag : 9783668820203 : 3668820201 : 31 Oct 2018 : Essay from the year 2018 in the subject Biology - General, Basics, language: English, abstract: The aim of this paper is to investigate the change in mass potato strips over a period of two hours when immersed in distilled water (hypotonic solution) and salty water (hypertonic solution). Research Question: How does the size of potato strips when immersed in both distilled water and salty water change over a period of 2 and half hours measured at 30 minutes intervals? Background Information: Osmosis is one of the physiological processes in living organisms, among them active transport and diffusion. Osmosis is the movement of water molecules from a region of low concentration to a region of high concentration across the semi-permeable membrane. In plants it makes cells to be turgid while in animals it offsets the osmotic pressures in the cell. Plant cells are hypertonic because they have a cell sap, so w
