why we should use mesh render for object and what is the use of it?

i am beginner to learn game developing and i could not understand,what is the use if mesh render and what does it means and how to generate the mesh render?please,clarify me in simple words?

You only need a mesh renderer on an object if you intend to have a mesh attached to the object which is used for rendering that mesh on camera. The Mesh Renderer takes the mesh from the Mesh Filter and renders it according to the object’s Transform position/rotation/scale.
