Here's a breakdown:

* Solute: The substance that dissolves in a solvent to form a solution.

* Solvent: The substance that dissolves the solute.

* Solution: The homogeneous mixture formed when the solute dissolves in the solvent.

Example:

* Sugar (solute) dissolves in water (solvent) to form a sugar solution (solution).

The solute is evenly distributed throughout the solution, meaning it's present in the same concentration in every part of the mixture.
