|
|
Water particles tend to move into the cell
|
|
|
There is no net movement of water particles
|
|
|
A solution that has the same solute concentration as another solution.
|
|
|
The overall concentration on both sides of the cell membrane remains constant.
|
Detailed explanation-1: -In the isotonic solution, the concentration of solvent and solutes of the solution is same as in the cytoplasm of the specific cell. This state allows the free movement of molecules across the membrane without changing the concentration of solutes on either side. Thus, the correct answer is option A.
Detailed explanation-2: -They do not have the same weight concentration.
Detailed explanation-3: -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-4: -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.
