TRANSPORT INTO AND OUT OF THE CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the concentration of solute is higher inside of a cell than it is outside of the cell, where will water move?
A
Water will have no net movement between the two areas
B
Water will flow out of the cell
C
Water will flow into the cell
Explanation: 

Detailed explanation-1: -Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.

Detailed explanation-2: -In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic.

Detailed explanation-3: -A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.
