  If you are provided with some vegetables to cook. You generally add salt into the vegetables during cooking process. After adding salt, vegetables release water. What mechanism is responsible for this?

Answer:

  On adding salt, the external medium is made hypertonic, i.e., concentration of water is lowered as compared to the concentration of water inside the cell. Thus, water is released from the vegetables due to exosmosis (water molecules goes out of the cell resulting in shrinkage of cell).
