Question

define hypertonic solution

Answer 1

A hypertonic solution contains a higher concentration of solutes compared to another solution. The opposite solution, with a lower concentration or osmolarity, is known as the hypotonic solution. In biology, scientist must describe cell contents compared to the environment. If a cell is placed in a hypertonic solution, the cell will be hypotonic. If the cytosol of the cell is a hypertonic solution, it means the environment is hypotonic, or more weakly concentrated. This is of great importance because solutes and water tend to flow or diffuse along their gradients. Two solutions mixed together will eventually become a single solution. If the solutions are separated by a permeable membrane that only allows water through, the solutions will become isotonic. 

Answer 2

hypertonic solution is the solution which consists of less solute and more solvent...n
osmotic pressure is less
