Intracellular fluids and the fluids surrounding cells in multicellular organisms are full of dissolved substances,including nucleotides,amino acids,proteins and ions.The total concentration of substances determines the colligative properties of a fluid.Osmosis is one of several such colligative properties.
a.Give the definition of osmosis.
b.Eukaryotic cells are aqueous solutions surrounded by semipermeable membranes.Consequently,incubation of a cell in a solution of lower osmotic pressure would cause the cell to swell up and burst.Discuss two solutions that have developed during evolution to solve this problem.
