  • Osmosis and Potatoes

    Osmosis and Potatoes

    Osmosis is a specialised form of diffusion. Water moves from an area of LOW concentration of Solute to an area of HIGH concentration of solute through a semi-or fully permeable membrane by the process. Water moves constantly through the cell’s membrane its estimated that about 250 times the volume of a single cell moves through 1 per second This continues until the solute concentration reaches equilibrium It is convenient to express the available energy per

    Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month, but if they didn't have water to drink they will be dead within a week. Hoping to postpone the inevitable, their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor

    Osmosis in Potato Chips

    The biological importance of water and its role in living organisms What is water? Water (from the Old English word water) is a colourless, tasteless, and odourless substance that is essential to all known forms of life and is known also as the most universal solvent. Water has a very simple atomic structure, the structure consist of two hydrogen atoms bonded to an oxygen atom, which can also be related to as hydrogen oxide.

    Osmosis with Potato Chips

    My Investigation on osmosis Osmosis is a special kind of diffusion. While diffusion can describe the movement of any kind of molecule, osmosis is only about the movement of water molecules. To show this diffusion I will be using potato discs, of the same size and mass, in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar

  • Osmosis

    Osmosis

    Osmosis Osmosis is just a special case of diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through, but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions, water moves through it in both directions at

    THE IRISH POTATO FAMINE Pre-Famine History The potato was introduced to Europe sometime in the 16th century. There are many theories on how it arrived, but the one with the most credibility is from a case study done by Theresa Purcell. She explains how the white potato, also known as the Irish potato, originated in the Andean Mountains and was brought to Europe by the Spaniards. The potato was originally classified in the same family

    Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece, 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent, the other

I think I took easily enough results for the amount of concentrations that I was using, and the time that I used for the experiment to last was enough to allow sufficient osmosis to occur.
