Answer:
Explanation:
Water tends to move in nature. This movement is facilitated by an osmotic gradient created as a result of OSMOSIS. Osmosis is the movement of water from a region of low solute concentration (high solvent concentration) to a region of high solute concentration (low solute concentration) through a semi-permeable membrane.
Salt contributes to the tonicity of the soil it was sprinkled in the sense that it makes the solute concentration of the soil higher (hypertonic) than that of the plant cell (hypotonic). This creates an osmotic gradient causing the movement of water from the plant cell into the road containing salt in order to form an osmotic balance. The water passes through the cell membrane of the plant cell which acts as the semi-permeable membrane in this case.
The movement of water out of the cell will eventually make the plant cells around that road area shrink (reduce) and likely die, due to loss of water content.
