suspension particles can be seen through a microscope
It can be seen through microscope, but it can't be seen through naked eyes because it is way too small to see because there are hundreds of particles in a single strand of your hair. So it is completely impossible to see with the naked eye.
Solution
A colloid is a substance that has tiny particles that do not settle. These particles are large enough to reflect light, therefore the substance's color is shown. An example may be milk because the milk's particles can not be seen individually, but all of them make up a color.
Colloid particles are smaller than suspensions particles.
A colloid is a homogeneous mixture in which particles are mixed together but not dissolved.
No, an electron microscope is needed to see a virus.
No, ketchup is not a solution because in a solution you can't see the particles but in ketchup if you look with a microscope you can see the particles. Making ketchup a colloid!
Solution
Solutions are mixtures on an atomic or molecular level; the mixture is so fine grained that you could never see it with a microscope. All you would see is a homogeneous substance. Colloidal suspensions contain tiny particles that you might be unable to see with the unaided eye, but which you could see with a microscope.

Yes, I think

Suspension has particles, same as colloids. However, the particles in a suspension do not settle down but if is no so for the colloid.
a solution is a well-mixed mixture containing a solvent and at least one solute that has the same properties throughout. a colloid is a mixture containing small, undissolved particles that do not settle out.
By dialysis
It is actually called colloid.
