Explain why a cucumber shrivels up when it is placed in a concentrated solution of salt.

Interpretation Introduction

Interpretation: The reason for why cucumber shrivels up when it is kept in a concentrated salt solution should be briefly explained.

Concept introduction:

Osmosis takes place when solvent molecule passes through a semipermeable membrane from solution having low concentration of solute to solution having high concentration of solute.

The pressure that opposes osmosis is known as osmotic pressure.

Explanation of Solution

Osmosis takes place when solvent molecule passes through a semipermeable membrane from solution having low concentration of solute to solution having high concentration of solute.

When cucumber is kept in a concentrated salt solution, osmosis takes place. Here, the water contains high concentration of salt whereas inside the cucumber the concentration of salt is very low...
