    hypertonic, hypotonic or isotonic. My hypothesis for this experiment was that the 0.0 to 0.3 molarity solutions would be hypotonic to the potato tissue, the 0.4 molarity solution would be isotonic and the 0.5 & 0.6 molarity solutions would be hypertonic. If the sucrose solution increased then their...

    : Discussion When the potato gains weight it was in a hypertonic solution, and when the potato loss weight it was in a hypotonic solution. If the potato would not have changed weight it would have been an isotonic solution, but that was not the case in this experiment. The potato either gained, or...

    gradient in different ways.  In a hypertonic solution there is a higher concentration of the solute than in the other solution.  Therefore, when the cell is put into a hypertonic solution, the water diffuses out of the cell which causes the cell to shrivel.  In a hypotonic solution, the solution has a low...

    , & Isotonic The above graph is similar to that of Figure 1.3, but this has labeled which solutions were hypertonic to the potato cytoplasm, which were hypotonic, and which was isotonic. As the concentration of the sugar increases, the more mass the potatoes would lose. This would make the...

  12. Biology

    referred to as dynamic equilibrium. Hypothesis Solution A is hypertonic to the potato; the potato submerged in Solution A will weigh more than the potatoes in the hypo/isotonic solutions. Solution B is hypotonic to the potato, so the potato will weigh less comparatively. Solution C is...

  13. Sports Drinks and Their Effectiveness

    of sports drinks: isotonic, hypotonic, and hypertonic. Isotonic sports drinks quickly replace fluids lost by sweating, and supply a boost of carbohydrates; they are also the choice for most athletes. For those athletes that replace fluids without the boost of carbohydrates, hypotonic drinks would be...

  14. Cell Stucture

    cell is in an environment that is hypertonic, the free water concentration is greater inside the cell while the solute concentration is higher outside. The net diffusion of water is out of the cell. In the case of a cell lacking a cell wall (animal cell), a hypertonic environment causes the cell to shrink...

  15. Determining the Osmotic Potential

    Introduction Now, the goal of this lab was to find the osmotic potential of the potato cells. Each of the five solutions can either be hypotonic, hypertonic, or isotonic to the potato cell. If a solution is hypotonic, then water will flow into the cells causing the cells to expand and theturgor pressure...

    How does the mass of a potato slice change when it is put into distilled water, tap water or salt water? Background: In this lab we will find out how water with different concentrations affects the mass of a potato slice when the slice is soaked in the water. In this lab the effects of osmosis will...

  18. Cell Membranes: Osmosis and Diffusion

    we refer to an isotonic solution, which means there is not net movement of water crossing the membrane in animal cell while plant cell will tend to flaccid. (Brooker et al., 2010) If instead, the concentration outside the cell is higher than inside; we call those solutions hypertonic and are not ideal...
