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

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

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

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

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

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

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

This experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential

In the mid-1800s, Ireland was a nation which depended on agriculture. The Irish were among the poorest people in the world, relying on crops to feed their families. The Great Famine, or An Gorta Mór, commenced with the potato failure in 1845. It lasted for six years and caused the deaths of over one million men, women and children. It also led to a huge increase in emigration with two million people fleeing the country in the search of both food and a life free from corruption. The Great Famine was

Lay 's chips are sold under division of Frito-lays Inc, which itself is owned by PepsiCo. Inc as a result of 1965 's merger. In early 1930s, Herman W. Lay started his snack

most noticeably awful starvations of present day history. For a long time, Irish workers had relied on upon potatoes as virtu-partner their sole wellspring of sustenance. From 1845 to 1848, a plant growth destroyed about the greater part of Ireland's potato crop. Out of a populace of 8 million, around a million individuals kicked the bucket from starvation and ailment throughout the following few years.During the starvation years, around a million and a half individuals fled from Ireland. Most went to

fungus called phytophthora infestans drifted over the fields of Ireland. (The History Place 1) Soon after, the fungal spores settled on potato plant leaves, which fermented, giving the fungus what it needed to live. (The History Place 1) The fungus soon spread to all the potatoes in Ireland, causing them to become black and rotted. (The History Place 1) As the potato blight in Ireland continued through the years, the Irish began the long journey to America in hopes to begin a new life away from the

sizes and lengths potato cylinders and applying them to different concentrations of sucrose(0%, 10%, 20%, 40%) in small beakers then measuring the change in mass of the potato cylinders afterwards. Maintaining all variables unchanged such as pH, same size, and a constant temperature. time taken for all potato cylinders will be 30 minutes. Hypothesis If the potato cylinders were put in sucrose concentration where the water potential is higher than the water potential that of the potato itself that would

goals and central questions that has to do with the project is mostly trying to determine the isotonic concentration of the salt in potato roots and the use of the ideal soil salt conditions for the potato plant growth. In part 2, we had to test the enzyme activity that is in the was involved in the potato, so we can also determine the ideal soil pH conditions for the potato plant growth. In part 3, we were able to test absorb the leaf pigment at various wavelengths that determine the optimum light absorption

major Homefront complication within WWI. In Germany, potatoes were the main source of food which became problematic in 1916, as a decrease in temperature before the harvest, coinciding with the seizing of one million horses by the army caused the potato crops to become inedible; as the farm equipment needed was unusable, as farming horses were seized, and unsuitable weather prevailed. Furthermore, German trade was halted by the British Naval Blockade, preventing the imperative importation of goods
