CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An effect of osmosis where the outside solution has a higher concentration than the solution inside the cell. Movement of water molecules out of the cell causes it to shrink.
A
hypertonic
B
isotonic
C
hypotonic
D
homeostatic
Explanation: 

Detailed explanation-1: -Such, solution is said to be hypertonic . In such a case, the water molecules move from inside to the outside of the cell through the cell membrane. This process is called as exosmosis and it occurs when solute concentration inside the cell is lower than outside.

Detailed explanation-2: -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.

Detailed explanation-3: -A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

Detailed explanation-4: -Explanation: A hypotonic environment would mean that the concentration of solute is higher inside the cell than outside, or that the concentration of solvent (usually water) is higher outside the cell.

Detailed explanation-5: -Final answer: If a solution outside the cell is more concentrated so that the cell loses water to its environment and shrinks the external solution is said to be hypertonic to the cell contents.
