Deciphering The Osmolarity(concentration of a solution) of a Potato Cell including the concept of Water Balance. Investigation Question Determine the osmolarity of a potato? Background In the two day lab performed in class, we worked with a potato commonly known as White Potato but its scientific name is “Solanum tuberosum”(New World Encyclopedia, 2017). We can tell it is White potato and not Sweet potato due to the color of the potato, Sweet potato is usually orangish red(Difference Between.net, 2011)

Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration

Qualitative Data: It was evident that after the potato cylinders were taken out from the sodium chloride solution after an hour, the ones that gained mass had increased in rigidity, becoming more turgid as well as appearing bigger than before. Their color also changed from distinct yellow to a lighter shade of yellow. On the other hand, potato cylinders that were put in a high concentration solution shrunk in size and they became shorter in length since they lost water. They felt softer, more flexible

The aim of this experiment was to find out how many sugar did the potato include, how many sugar did we have every day by eating the potato. To know the sugar that includes in the potato we have to compare the mass of the potato before and after the experiment with different concentration of sucrose solution. We went through our procedure, put the result into the data table and calculate the percent change to the graph. And get the osmolarity bass on the graph we have. The mass of the before the

will affect the mass of a Potato Investigation Background Information: In this investigation we are going to see how osmosis occurs in a potato and affects the mass by reducing or adding onto it. Osmosis is the diffusion of water between a semi-permeable membrane from a higher concentration to a lower concentration. Variables that can be explored in this investigation is how the concentration of salt solution could affect the mass as well as how the size of potato could affect the mass. Research

Data Presentation: Graph 1: Color vs Mass The solutions in the colors red, orange, and blue had final weights greater than their initial weights. The potato cores gained mass. The yellow, green, and purple sucrose solutions had initial weights was greater than their final weights. The potato cores loss mass. Table 1: Color vs Percent Change Color Percent Change red 5.22 % orange 10.81 % yellow -5.20 % green -1.56 % blue 9.45 % purple -1.81 % water 9.67 % Percent Change in Mass = Final Mass – Initial

initial and final masses of the potato pieces and the small bag of Visking tube. According to the table 1 and graph 1, the effect of concentration was identified as the concentration of sucrose increase the percentage change in mass of potato also increase because sucrose is hypertonic solution which means that it has a higher amount of particles dissolved in the solution, while a hypotonic solution such as water where there are fewer particles dissolved. When the potato was put in sucrose concentration

PARLE WAFFERS & FULLTOSS Potatoes used for making chips are stored in separate room (temperature less than the normal temperature). In that room, unwashed and unpeeled potatoes are manually put in the machine, from where they move to Destoner unit. PROCESS LAYOUT: 1. Destoner unit- wash potatoes in water. 2. Peeler unit- potatoes are peeled in this unit. It consists of 2 parts: Peeler and Screw. 3. Trimming table- on this table, thick potatoes are manually cut into 2 using a knife. 4. Bulk

Response At the beginning of the article, the author described a scene that more and more Irish people were pouring into America during 1845 to 1851 to draw forth the main topic. Then, the author pointed out four points to explain why the Irish potato famine was so serious. The first point was the loss of their homes and possessions to their indifferent landlords. The indifferent landlords extract the poor Irish people who were leading a harder life than before. The second point that the author

From the years 1845 to 1855 millions of adults and children fled over from Ireland to America, in order to escape the many issues their country was facing at this time. In my paper I will argue what lead to the potato famine and how this lead Irish families to seek refuge in American. In the 12th century England began their colonization over Ireland, this lead to many wars, confiscations and also rebellions. Finally after a series of fights between Ireland and England, England dominated over the

The Great Potato Famine By Jackson Keenan 11 The Irish did not eat potatoes for four years because of the Great Irish Potato Famine. Imagine not eating potatoes for four years. Famine, which is a low amount of food, lasted a four year period (1845-1849)and had a terrible impact on the country of Ireland. The country of Ireland still has not fully recovered from the famine.But after a while the Irish population decreased by 1 million. How did it start The Great Irish Potato Famine started

How the Potato Chip was Popularized Potato chips, known as America's number 1 favorite snack item. Packed in more lunches world wide and as the commercial line says you can't eat just one. In 2003, over 65,000 people were employed making potato chips. With retail sales of over 6 million dollars per year, chips have come a long way from their humble beginnings.(2) In the summer of 1853, George Crum was employed as a chef in Saratoga Springs, New York. He invented them by mistake in 1853 when a picky

Irish Genocide The Irish Genocide, also known as the Great Potato Famine, was the second deadliest disaster in Great Britain, with a death toll over 1 million. The Great Potato Famine started in September of 1845 and ended in 1852. It was located in Ireland and it took the population down by 20-25%. The Great Potato Famine was a genocide because the British took control of Ireland when a disease spread and ruined all of Ireland’s potato crops which was the main food at that time and caused a mass

Did you know that 1.5 billion bags of potato chips are consumed each year just by Americans? You may wonder, why are they so popular? Well, Potato chips taste good, appeal to Americans, and are an easy snack. You may not know, but potato chips have been around for over 150 years. They were originally created by George Crum in 1853. He invented them when a customer at his restaurant said that the french fries were too thick. He then made a thinner batch of them, but the customer was still

The many different varieties of potato have played an important role in the human diet for centuries. Central and South American civilizations such as the Inca relied on the potato. In the 1600s the potato was brought to Europe by Spanish conquistadors where it flourished as a crop throughout the continent. Today the potato is an important crop in over 100 countries and is grown on every continent except Antarctica. The United States produces more potatoes (442 million cwt in 2014) than any other

sodium in the water is equal to the amount of sodium in the potato cell. Sodium is a mineral found naturally in many foods, including fruits and vegetables. Your body needs some sodium to balance the amount of water in your cells and stimulate the production of nerve impulses and muscle contractions (HealthyEating.sfagte). An average potato weighs around 213 grams, and is a vegetable which is rare in sodium. About 1-3 percent of the potato is considered pure sodium which can also be a positive aspect

Why did the potato blight in the 1840s and 1850s cause little excess mortality in Scotland but catastrophic famine in Ireland? The outbreak of potato blight, phytophthora infestans, originated in America and rapidly spread to countries in Northern Europe including Britain and Ireland. Different countries were affected by varying degrees but none to the devastating extent of that in Ireland. The famine in Ireland or An Gorta Mór, the great hunger, was a catastrophic disaster that lasted from 1845

“Mrs. Potato Head” by Melanie Martinez is a song that addresses how society strives for perfection and influences our insecurities of our appearance. The lyrics in this song touches the struggle and pressure to maintain physical attractiveness. This song describes every individual as a real-life potato head doll. Mr. and Mrs. Potato Head are plastic potato dolls that can be decorated with a variety of plastic parts, hinting plastic surgery as a solution. First verse is, “If you weren’t born with

these varieties fit into one of seven potato type categories: russet, red, white, yellow, blue/purple, fingerling and petite.” Potatoes come in different sizes and shapes and each used for different purposes including fresh

Higher Concentration of Sucrose Lowers the Mass of a Potato Independent Variable: Concentration of Sucrose used Dependent Variable: Mass of each Potato after Experiment Constant: Size of Potato being used at room temperature Introduction We learned about hypertonic and hypotonic environments before this lab as well as what takes place during osmosis. Do potatoes loose or gain mass when soaked in specific solutions such as sugar or salts? Sugar is a large molecule and has low permeability
