Solution :-

(a) Plasmolysis: Movement of water takes place outside the cell which causes shrinking of cell cytoplasm away from its cell wall. Hypertonic solution causes the shrinkage of cell cytoplasm because to make the solution normal the water moves out of the cell. This process can be observed if we sprinkle salt over the cut raw onion.

(b) Higher water potential inside the cell builds up the pressure in the cytoplasm of the cell against the cell wall. This is called turgor pressure. This pressure causes
an increase in the size of the cell, but the rigidity of the cell wall prevents it from bursting due to this cell swell.
