If the fertilizer is placed around the root of a tomato plant, the leaves of the plant will shrivel and turn brown. This phenomenon in terms of tonicity is that;


  • inside the root cell is hypotonic since it contain more water than surrounding .

  • In the other hand the cell is hypertonic since it contain more solute from fertilizer.

  • Through osmosis water move out of the cell therefore the it turns to brown.
