Detailed explanation-1: -If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.

Detailed explanation-2: -The concentrated sugar solution in beaker B is hypertonic because the solution has a higher concentration compared to the raisin.

Detailed explanation-3: -Hypotonic solution refers to a solution containing a lower amount of solute in comparison to the solute concentration in other solutions, across a semipermeable membrane. Such a solution has a decreased solute concentration and a total movement of water in the cell.

Detailed explanation-4: -Hypotonic solution is a solution which has a greater concentration outside the cell and hypertonic solution is a solution which has a greater concentration inside the cell.

Detailed explanation-5: -A solution with a lower solute concentration as compared to a solvent is called a hypotonic solution. In contrast, a solution with a high solute concentration as compared to a solvent is called a hypertonic solution.
