Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment‚ its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

populations. The Irish potato clones were certainly low on genetic variation‚ so when the environment changed and a potato disease swept through the country in the 1840s‚ the potatoes (and the people who depended upon them) were devastated.Thesis: The Irish Potato Famine devastated the Irish population and economy as well as sowing the seeds of rebellion against England. 1st Point: Ireland dependent on potato • Families spent most time on cash crops to pay rent • Potato easy to grow‚ nutricious

Where as a cabinet shop does not need much MRO compared to Frito Lay.In contrast‚ a cabine shop or a machine shop keeps high raw materials‚ wip and final products in inventory since the order basis have variations. The demand for Frito Lay is not by order basis compared to a cabinet

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more
