    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...

  13. Osmosis: Potato Tuber Lab

    Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when...

  14. Finding the concentration of a Potato cell.

    Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute...

    lab, if the mass of potato is decreased, the solution is hypotonic; if the mass of potato is decreased, the solution is hypertonic. If the mass stays the same as initial mass, the solution is isotonic. 2. Since the concentration of 0.1 has a change in mass of 0, 0.1 is istonic. Potato cytoplasm and the...

    concentration of the solution the cell is placed in. In hypotonic solution, more water is present on the outside of the cell than the inside, which means the net diffusion of water is flowing inside the cell causing the cell to swell up. Hypertonic solutions on the other hand contain less water outside...

    respect to osmosis, animal cells, which do not have cell walls, absorb water from a hypotonic solution (concentration of solute lower than that found inside the cell) and will swell until they burst. In a hypertonic solution (concentration of solute higher than that found inside the cell), the animal...
