Definitions:

Concentration Gradient

The gradual difference in the concentration of solutes in a solution between two regions, often leading to diffusion.

Hypotonic

Referring to a solution that has a lower concentration of solutes relative to another solution, thereby causing water to flow into the cell by osmosis.

Hypertonic

A solution that has a higher solute concentration compared to another solution, leading to osmosis out of the cell.

Isotonic

Describes two fluids that have identical solute concentrations.
