DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a cell has the same concentration of dissolved particles of the cell, the the solution is ____
A
isotonic
B
hypertonic
C
hypotonic
D
hydroponic
Explanation: 

Detailed explanation-1: -The overall process is known as plasmolysis. An isotonic solution has the same solute concentration compared to the intracellular solute concentration. When a red blood cell is placed in an isotonic solution, there will be no net movement of water.

Detailed explanation-2: -An isotonic solution has the same concentration of dissolved particles as a cell. A cell in an isotonic solution will not change. A hypertonic solution has a higher concentration of dissolved particles than a cell.

Detailed explanation-3: -An isotonic solution is one that has the same concentration as another solution. If two solutions are separated by a semipermeable membrane, solution will flow in equal parts. As the concentration of solute and solvents are the same.

Detailed explanation-4: -If solute concentrations are equal between the environment and the interior of the cell, there will be no net gain or loss of H20 from the cell. Such a situation is called isotonic. Bacteria differ with regard to their osmotic needs.

Detailed explanation-5: -Here water can be called hypotonic solution and salt solution can be called hypertonic solution. The movement occurs to balance concentration and form equilibrium.
