  • Tonicity In Potato Strips

    Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells, potato strips and three unknown solutions (A, B, C). First three slides were prepared containing RBC’s and unknown solutions A, B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The...

  • Determing the Osmolarity of a Potato

    of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation, several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose...

    EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion, they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move, they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion, for example smell of cooking travelling around the house from the kitchen...

    Diffusion and Osmosis Introduction Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic, hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A, Solution B, Solution C, and Solution D. Since potato cells were used for this type of experiment, in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl.

Diffusion occurs when certain substance, such as an ion, is more concentrated on one side of membrane. If the membrane allows this ion through, the ions will move from the more concentrated side to the less concentrated side until reaching equilibrium.

    A potato battery is a type of electrochemical cell. An electrochemical cell converts chemical energy into electrical energy. In the potato battery, there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity, yet keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move (generate current). It's...
