Question

Celery stalks that are immersed in fresh water for several hours become stiff. Similar stalks left in a 0.15 M salt solution become limp. From this we can deduce that the fresh water_____.

Answer 1

is hypertonic and salt solution is hypotonic to the cell.

Step-by-step explanation:

If extracellular fluid has lower value of osmolarity as compared to fluid inside cell, it is said to be hypotonic to cell, and net flow of water will be into cell.

Hence, in salt solution , the celery stalks becomes limb which means they are hypotonic to salt solution.

If extracellular fluid has a higher value of osmolarity as compared to cell’s cytoplasm, it is said to be hypertonic to cell, and water will move out of cell.

Hence, in water, the celery stalks becomes stiff which means they are hypertonic to water.
