Summary Introduction
To review:
The effects of hypertonic solution that surrounds the animal cells.
Introduction:
In biology, tonicity is defined as the relative concentration of the solute present inside the cell (cytosol) to the concentration of the solute present in the solution surrounding the cell. Tonicity can be hypertonic if the outside solution has a higher concentration of solutes compared to the cytosol of the cell. On the contrary, it will be called hypotonic if the solution outside has lower concentration of solutes as compared to the cytosol. Also, Isotonic is a condition when the concentration of solutes inside the cell is equal to the concentration of solutes outside the solution.
