DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water moves out of a cell when the cell is placed in a
A
hypotonic solution
B
isotonic solution
C
hypertonic solution
Explanation: 

Detailed explanation-1: -When a cell placed in hypertonic solution (has more solutes that cell), the cell will shrink because water moves out, firstly from the cytoplasm and then from the vacuole. This process is called as exosmosis which leads to the plasmolysis .

Detailed explanation-2: -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-3: -When a cell is kept in hypertonic solution for a long time it shrinks. The water inside the cell moves out as the concentration outside the cell is higher. As a result, the cell shrinks. This is also known as plasmolysis.
