Verified step by step guidance

1. Understand the terminology related to solutions: a solution is a homogeneous mixture composed of two or more substances.
2. Identify the components of a solution: the substance that dissolves is called the solute, and the substance that dissolves the solute is called the solvent.
3. Recognize that a suspension is a heterogeneous mixture where particles are dispersed but not dissolved, and a precipitate is a solid that forms and settles out of a solution.
4. Since the question asks for the particles of matter that are dissolved, focus on the term that describes the dissolved substance, which is the solute.
5. Therefore, the correct term for particles of matter that are dissolved in a solution is 'solute'.
