A cell with a 20% salt solution is placed into a beaker of pure water. What will happen to the cell?
A
It will shrink
B
Plasmolysis
C
No change
D
Cytolysis
Explanation: 

Detailed explanation-1: -Salt Sucks, Cells Swell Water in cells moves toward the highest concentration of salt. If there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt.

Detailed explanation-2: -A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.

Detailed explanation-3: -When a cell is placed in concentrated salt water (hypertonic solution), it is seen that cell has more water content than the salt solution. As a result, the water will move from its higher concentration to lower concentration without any expense of energy (passively).

Detailed explanation-4: -Water will move toward the area with the greatest solute concentration. For example, if you place a cell in a salty solution, the water in the cell will move out of the cell, causing the cell to shrink. A cell that is 1% salt is placed in a solution that is 3% salt.
