Kowles  \nSaint Mary‟s University of Minnesota, Biology Department  \n700 Terrace heights, Winona, MN 55987  \nAbstract: Cell water relationships are important topics to be included in cell biology courses. Differences exist in the control of water relationships in plant cells relative to control in animal cells. One important reason for these differences is that turgor pressure is a consideration in plant cells. Diffusion and osmosis are the underlying factors involved in the control of water in plant cells; however, additional attention must be given to osmotic pressure, osmotic potential, and water potential. This discussion shows how these parameters relate to each other, and how they are explained by thermodynamics and the universal gas laws. Detailed laboratory exercises are described that demonstrate these principles. The laboratory exercises include data collection, graphing of data, statistical analysis of data, and calculations of osmotic potential and diffusion pressure deficit from the data.  \nKeywords: Turgor, osmotic pressure, osmotic potential, water potential, diffusion pressure deficit  \nIntroduction  \nCell water relationships are deemed by most cell biologists to be an important topic for inclusion in cell biology courses. Still, some cell biology textbooks do not thoroughly cover the topic. In most textbooks, the topic is at least discussed with an explanation of osmosis; however, some of these discussions are without any reference to the thermodynamics involved. In other cases, there is a complete omission of the concept of turgidity. The control of water in plant cells is considerably different from the control in animal cells because of cell walls and turgor, a topic not always covered in detail in some cases.  \nAlmost all of the textbooks reviewed have general explanations of osmosis. Pollard and Earnshaw (2002), however, did not include any discussion on the subject. In addition to osmosis, a number of textbooks also included some discussion on water relationships in plants by providing descriptions of plant cell walls, vacuoles, turgor, and plasmolysis. The concept of thermodynamics, however, was not related to water movement in these textbooks (Bolsover et al., 2004; Lewin et al., 2007; Karp, 2008; Alberts et al., 2010) . Cooper and Hausman (2007) included an excellent discussion of the contrast of water relationships between plant and animal cells. Becker et al. (2009) additionally discusses the 2nd Law of Thermodynamics, free energy, and entropy. The most quantitative descriptions of water movement were found in  \noutdated textbook editions that are probably out of print (Wolfe, 1993; Tobin and Morel, 1997) .  \nBackground Information  \nOsmosis, in a very technical sense, is the movement of water across a membrane whereby thenet movement occurs from a lesser negative water potential to a more negative water potential. The following discussion explains the basis of that definition. Osmosis is an event of diffusion, and it occurs because of the random movement of molecules due to kinetic energy. Diffusion is the tendency of molecules to undergo a net movement in the direction of lesser concentration. The rate of diffusion is proportional to one over the square root of the molecular weight of the molecule involved. Temperature, the distance to travel, and the area of diffusion are other factors involved in the rate of diffusion. A diffusion gradient, therefore, will result in a substance undergoing a net movement from a region of greater concentration (C 1) towards a region of lesser concentration (C2) . The diffusion of solute particles is similar to the diffusion of gases, except that the particles are in a solvent. Hence, gas laws can be applied in order to analyze the movement of solutes.  \nOsmosis generally refers to the net movement of water across a membrane. Osmosis occurs, for example, when an aqueous solution is separated from pure water by a semi-p","cbCain8TiHI8LzPJ","https://ap.wps.com/l/cbCain8TiHI8LzPJ","pdf",655897,9,"English","# Abstract\n## Introduction\n## Background Information","[{\"question\":\"What factors control water relationships in plant cells compared with animal cells?\",\"answer\":\"Plant cells emphasize turgor pressure and distinct roles of cell walls, making water control substantially different from animal cells.\"},{\"question\":\"How do diffusion and osmosis contribute to regulating water in plant cells?\",\"answer\":\"Diffusion and osmosis are underlying processes, but additional parameters such as osmotic pressure, osmotic potential, and water potential must also be considered.\"},{\"question\":\"What do the laboratory exercises described in the work involve?\",\"answer\":\"The exercises include collecting data, graphing it, performing statistical analysis, and calculating osmotic potential and diffusion pressure deficit from the data.\"}]","Regulation of Water in Plant Cells - Abstract and Laboratory Study | PDF",23,{"code":4,"msg":80,"data":97},[98,102,106,110,115,120,123,128,132,135,139],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":99,"show_sort_weight":100,"slug":101},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":107,"show_sort_weight":108,"slug":109},"Exam",70,"exam",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":113,"slug":114},5,"Comic",60,"comic",{"id":116,"doc_module":4,"doc_module_name":25,"category_name":117,"show_sort_weight":118,"slug":119},6,"Technology",50,"technology",{"id":84,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":121,"slug":122},40,"healthcare",{"id":124,"doc_module":4,"doc_module_name":25,"category_name":125,"show_sort_weight":126,"slug":127},8,"Research & Report",30,"research-report",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":129,"show_sort_weight":130,"slug":131},"Religion & Spirituality",20,"religion-spirituality",{"id":130,"doc_module":4,"doc_module_name":25,"category_name":133,"show_sort_weight":130,"slug":134},"World Cup","world-cup",{"id":136,"doc_module":4,"doc_module_name":25,"category_name":137,"show_sort_weight":136,"slug":138},10,"Lifestyle","lifestyle",{"id":140,"doc_module":4,"doc_module_name":25,"category_name":141,"show_sort_weight":111,"slug":142},19,"General","general"]
