They are not the same. If you pass a suspension through a filter paper, all the solid that was in suspension is left behind on the paper. A solution doesn't have any solid bits in suspension - it is all liquid. It will go through a filter paper without leaving any thing behind.
A solution is a homogeneous liquid, a suspension is not homogeneous. A suspension is not a true solution.
seawater solution or suspension
A colloidal suspension is neither a mixture nor a solution.
Orange juice from concentrate would be a solution, although real orange juice is neither a solution or a suspension. The major difference between solution and suspension is that a solution is a homogeneous mixture, and a suspension is heterogeneous.
seawater solution or suspension
A mixture may be a solution, a suspension, etc.
Biscuit is a solid, not a solution or suspension.
suspension
Suspension will have residue after filtration, but solution will not.
A solution is a homogeneous liquid, a suspension is not homogeneous.

It is a solution.
