Ответ:

У такому випадку ми стикаємося з явищем осмотичного тиску. Осмотичний тиск виникає, коли різниця в концентрації розчинених речовин по обидва боки мембрани стає недостатньо великою для досягнення рівноваги. У даному випадку, коли клітина знаходиться у водному розчині з вищою концентрацією солей, вода почне виходити з клітини у спробі зрівняти концентрацію розчинених речовин по обидва боки мембрани. Це може призвести до скорочення або зморшкування клітини, оскільки вона втрачає воду. Процес, коли вода переходить через мембрану від розчину з меншою концентрацією розчинених речовин до розчину з вищою концентрацією, називається осмозом.
