  • Potato Osmosis Investigation

    1779 Words  | 8 Pages

    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

  • Potato Osmolarity Experiment

    303 Words  | 2 Pages

    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

    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

    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

  • The Irish Potato Famine In America

    1458 Words  | 6 Pages

    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

  • Water Potential Osmosis Experiment

    743 Words  | 3 Pages

    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

  • Sucrose Concentration Lab Report

    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

  • The Great Famine In Ireland In The 1800's

    2807 Words  | 12 Pages

    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

    him that blood isn’t ketchup, he wasn’t listening. He was coming right at me. I dodged to the left, and jumped into the corn stalks. It started axing the stalks away. I ran as fast as I could toward my house, but I could hear the humming of the potato above. After about six minutes, I was out of the corn field with my house only a few steps ahead. I looked behind me just in time to see the axe being swung toward my arm. I moved just in time. Through the grass and up the steps I ran, and slammed
