Celery stalks that are immersed in fresh water for several hours become stiff and hard. Similar stalks left in a 0.15 M salt solution become limp and soft. From this we can deduce that the cells of the celery stalks are 1) hypotonic to both fresh water and the salt solution. 2) hypertonic to both fresh water and the salt solution. O 3) hypertonic to fresh water but hypotonic to the salt solution. 4) hypotonic to fresh water but hypertonic to the salt solution. 5) isotonic with fresh water but hypotonic to the salt solution.

Answer :- =>(4) Hypo tonic to freshroaten but hyper tonie to salt solution, “Explanation; It water entera into the Celery stalks then these will & became Stiff and hard. And if water goes. out then the stalks will became timp and softi • The freshwater is hypotonic to the Stalks, so that writer enters into the ellls. • The 0.15 m salt solution is hypertonie to the stalka ;so that C cellular water goes outside the cells, and it became cimp and soft. Hence, the freshwater is hypotonic to the stalks and hypertonic to 0,15 m salt solution:
