Here's why:

* True: Particles in a suspension are larger than those in a solution. This is the key difference between the two.

* False: Particles in a suspension can be seen with the naked eye or under a microscope. They are large enough to scatter light, giving the suspension a cloudy or opaque appearance.

Here's a breakdown:

* Solutions: The solute particles are so small (usually molecules or ions) that they dissolve completely in the solvent and are invisible to the naked eye. The mixture is homogeneous.

* Suspensions: The solute particles are larger and do not dissolve. They remain dispersed throughout the solvent, but will settle out over time. They are visible as a cloudy or opaque mixture and can be filtered out.

Example:

* Solution: Salt dissolved in water. The salt particles disappear, and the mixture looks clear.

* Suspension: Sand in water. The sand particles are visible, and the mixture looks cloudy. The sand will settle to the bottom if left undisturbed.
