Active Transport is only done for nutrients and all cuz the opposite process of Osmosis ( much like the active transport is) Reverse Osmosis!!

and you have to tell the similarites so
1. they both will lose water
2. they both will either lose size or become flaccid
3.some of the concentrated solution enters the cell ( but remains out of cytoplasm ) so here it will also enter (<-------not sure about this one!!)
