| Osmosis practical Observation |
Conclusion :-
When Potato bath is placed in Hypotonic solution due to osmosis the water flows from petridish containing hypotonic solution to the hypertonic solution in the potato bath and water level increases.
When potato bath is placed in hypertonic solution due to osmosis the water flows from potato bath containing hypotonic solution to the hypertonic solution in petridish and water level decreases.
Water flows from petridish to potato bath containing concentrated NaCl (Hypertonic solution)
