saturated, unsaturated and supersaturated

Solubility is defined as the maximum amount of solute dissolved by a given amount of solvent at a definite temperature.

The solubility of the given substances in a given solute is temperature-dependent.

Solution containing the maximum amount of solute at room temperature is saturated. When more solute is added into the solution the solute will no longer dissolve.

If the solution contains the maximum amount of solute at an elevated temperature the solution is supersaturated. When more solute is added into the solution, crystals will form.

If the solution contains less quantity of solute than what can be dissolved at room temperature it is unsaturated. When more solute is added into solution the solute dissolves.

    ate the saturated solution will still form crystals, right? because if you add some more solute, it wouldn't dissolve, therefore the undissolve one are called crystals. Am I right?... I just want to clarify things.
