Acell with a concentration of 1.5% nacl is immersed in a solution with a concentration of 5.5% nacl. what will happen to the cell after being immersed in the solution for many hours?

This question depends on whether its an animal cell or a plant cell
For animal cell, the water molecules will move from the cell sap out to the solution by net movement of osmosis through a partially permeable membrane. it eventually becomes crenated.
For plant cell, water molecules will move from cell sap to the solution and eventually turns flaccid or plasmolysed
