Answer: Hypertonic
Step-by-step explanation:
Hypertonic condition can be defined as the condition where the solution has higher osmotic pressure than other solution.
It can also be defined as the condition in which the number of solutes outside the cell is greater than inside of the cell.
In this condition, there is a movement of particles from the outside of the cell to inside due to which the cell swells up and dies.
Here, the same happened with the plants of fresh water in which the salt concentration due to hurricane was high outside the cell and it flowed inside the cell and the cell busted and died.
