TRANSPORT INTO AND OUT OF THE CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the water concentration in a cell is 90% and the water concentration outside the cell is 95%, what direction will the water move?
A
Into the cell
B
Out of the cell
C
The water will not move
Explanation: 

Detailed explanation-1: -The concentration of water inside the cell is higher compared to the outside than the water will flow. Out of the cell, causing it to shrink at the concentration of the water is the same on the inside of the cell and the outside. Then the water will flow in both directions and the cell will remain the same.

Detailed explanation-2: -The cell will contain 95% water and the environment will contain 94% water. The water will move out of the cell it is a Hypertonic Solution.

Detailed explanation-3: -If a cell encounters a hypotonic environment, (like pure water for instance), water will diffuse into the cell and the cell will begin to swell. This can of course lead to an explosion of sorts.

Detailed explanation-4: -If the water concentration is higher outside the cell then we say that the cell is immersed in a hypotonic solution. The concentration inside the cell is hypertonic to the outside. Water will enter the cell in order to make the water concentrations equal on both sides. As a result, the cell will lyse.

Detailed explanation-5: -The cell has higher water concentration, which means it has less solute concentration than the surrounding medium. Such, solution is said to be hypertonic.
