TRANSPORT INTO AND OUT OF THE CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What will happen if a cell that is 20% water is placed in a beaker that is 70% water?
A
Nothing will happen
B
Water will enter the cell and cause it to swell-Hypotonic
C
Water will leave the cell and cause it to shrink-Hypertonic
D
Water will stay in the cell
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: -If a cell is placed in a hypotonic solution, the cell will swell and burst.

Detailed explanation-3: -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.

Detailed explanation-4: -A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis. These three examples of different solute concentrations provide an illustration of the spectrum of water movement based on solute concentration through the process of osmosis.
