|
It describes how an intracellular solution can change the volume of a cell by affecting osmosis.
|
|
|
A solution’s tonicity often directly correlates with the osmolarity of the solution
|
|
|
A solution with low osmolarity has a greater number of water molecules relative to the number of solute particles
|
|
|
The tonicity of a solution also refers to the effect of a solution on a cell volume
|
Detailed explanation-1: -“Tonicity is the ability of a solution to affect the fluid volume and pressure in a cell. If a solute cannot pass through a plasma membrane, but remains more concentrated on one side of the membrane than on the other, it causes osmosis.”
Detailed explanation-2: -In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell.
Detailed explanation-3: -Tonicity is the concentration of a solution as compared to another solution. Concentration describes the amount of solutes dissolved by a solution. If a solution has a higher concentration of solutes (less water) than another it is said to be hypertonic.
