Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then we cut the potato using the

The Irish Potato Famine Have you ever thought that one day all of the potatoes could go bad? Unfortunately it’s true.The potato famine or known as the Great hunger was in Ireland until 1845-49. People of all ages were affected.Since the soil was poor‚ potatoes didn’t grow like they’re supposted to. The cause‚ a failure of the Irish potato crop due to an infestation of Phytophora infestans‚ a microscopic fungus‚ also called the potato blight.They think that the disease was brought him by an American

Global Variations in the Potato Crisps and Potato Chips Market It’s fair to assume that consumer snacking habits are likely to differ from country to country‚ particularly across different regions and cultures. A clear example is the consumption of potato crisps / potato chips which can be seen in the bar chart below. 86% of consumers throughout the USA and France consume potato crisps / potato chips closely followed by 84% of GB consumers. On the other end of the scale is the Chinese market

Ireland suffered greatly during the potato famine in the 1840s. Around one million people died of starvation or disease. Many immigrated to the United States to try to escape the horrid that surrounded them in Ireland.Food was considered the most deadly weapon in a war. Starvation was the leading cause of death in a war. If you had control of the food supply‚ your army had the greater advantage. Your enemies would most likely fall from starvation‚ enviably you would win. Food also gave the soldiers

An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚ weight of tubers

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)

How the Potato Changed the World In today’s world the potato is the fifth most vital crop universal‚ it follows wheat‚ corn‚ rice and sugar cane. However in the 18th century the potato was an amazing novelty‚ part of a global environmental fit started by Christopher Columbus. Roughly 250 million years ago‚ the world consisted of a single giant landmass now known as Pangaea. Physical forces broke Pangaea separately‚ creating the continents and hemispheres well-known today.
