DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Animal cells will shrink and shrivel, when a cell is placed in a
A
Isotonic solution
B
Hypertonic solution
C
Hyportonic solution
D
Hypotonic solution
Explanation: 

Detailed explanation-1: -In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.

Detailed explanation-2: -When an animal cell is placed in a hypertonic solution, then water moves out of the cell as a result of exosmosis. So, when an animal cell will be placed in a hypertonic solution then it would lose water and shrink.

Detailed explanation-3: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-4: -When an animal cell is placed in a hypotonic solution the animal cell will burst due to the net movement of water from the solution into the cell. This net movement was caused by a lower solute concentration in the solution than in the cell.

Detailed explanation-5: -Animal cells tend to do best in an isotonic environment, plant cells tend to do best in a hypotonic environment.
