Definitions:

Plasmolysis

The process in which cells lose water in a hypertonic solution, resulting in the shrinkage of the cell membrane away from the cell wall.

Hypertonic

A solution that has a higher concentration of solutes compared to another solution, leading to potential osmotic movement of water out of a cell.

Extracellular Fluid

Fluid that exists outside the cells of an organism, including blood plasma, lymph, and interstitial fluid, providing a medium for transport of nutrients and waste.

Solute Concentration

The amount of a substance dissolved in a unit volume of solution, often referred to in terms of molarity, molality, or mass percent.
