TRANSPORT INTO AND OUT OF THE CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A cell with a 10% salt solution is placed into a beaker with a 40% salt solution. How will water move?
A
It will leave the cell
B
It will enter the cell
C
It will move in and out equally
D
There will be no movement
Explanation: 

Detailed explanation-1: -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-2: -For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response.

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: -What happens to plant cells placed in a high salt (10%) solution? Water diffuses out of the cells and they shrink.

Detailed explanation-5: -Final answer: When the cell when it is placed in salt solution, it will shrinks.
