Definitions:

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.

Hypertonic

A Hypertonic solution is one in which the concentration of solutes is greater outside the cell than inside it, leading to cell shrinkage.

Osmotic Pressure

Osmotic pressure is the pressure that must be applied to a solution to prevent the inward flow of water across a semipermeable membrane, driven by differences in solute concentration.

Turgor Pressure

Turgor Pressure is the force within the cell that pushes the plasma membrane against the cell wall, crucial for maintaining plant cell structure and rigidity.
