    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...

    showed that the potatoes were affected by hypertonic and hypotonic osmosis. The potato in salt water decreased in its mass by hypertonic by at least 0.2 to 2%. The potato in regular water increased in it's mass by hypotonic by at least 0.6 to 4%. The potato represents a cell being affected by osmosis...

    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...

    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...
