Whats the difference between a reagent and a solution?

ex:benedict’s reagent,fehling’s solution..(comes in biochemistry for testing glucose presence)
why not say benedict’s solution and fehling’s reagent?!
What is reagent?
What is solution?
searched everywhere..couldnt find answer:(

devi this is very simple do not make it complicated ,

chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions and that have a unique and defined chemical structure.

and reagent is simply a substance that is added to verify the presence of a chemical more specifically it is to cheak whether the reaction occurs or to bring about a reaction

Reduction of Fehling’s solution
