What would happen to an animal cell with an internal salt concentration of 0.8% if it were placed in a salt solution with a concentration of 20%?

A. Not enough information to be able to tell

B. The cell would swell and burst

C. The cell would not be affected

D. The cell would shrink

An animal cell with an internal salt concentration of 0.8% will shrink if it were placed in a salt solution with a concentration of 20%.

OSMOSIS:

Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration via a semipermeable membrane. Movement of water in osmosis is based on concentration gradient i.e. difference on concentration of solute inside and outside the cell. Water will move from a cell with more water or less salt concentration i.e. the internal cell with 0.8% salt concentration to a solution with less water or more salt concentration i.e. 20% salt concentration. This will cause the cell to lose water to its external solution, and, hence, shrink.
