  • Bio Lab

    (Osmolarity: The Test).Hypertonic, hypotonic and isotonic are three terms used when referring to two solutions separated by a selectively permeable membrane (Morgan & Carter 2011). Hypertonic has a greater concentration of solutes that cannot cross the membranes. Hypertonic has a low concentration...

    solution is hypotonic, and water will move from the solution into the cell. If the surrounding solution has a higher concentration of dissolved molecules than the cell, the solution is hypertonic. In that case, water will move from the cell out into the surrounding solution. An isotonic solution is when...

    inside of the cell, this is called a hypotonic solution. In hypotonic solutions, when water moves into the cell they burst, which is known as lysis. A hypertonic solution is when the concentration of outside the cell is higher than the inside of the cell. In hypertonic solutions, water moves out of the...
