Just wondering why a standard , plain jane light fixture doesn't have a terminal for the ground wire ? All the switches and outlets have it.

Porcelain or plastic is none conductive. There would be no shock hazard. Switches and receptacles can have metal cover plates and could have a shock hazard.

I assume receptacles have ground terminals because there is an exposed screw connected to the frame, same for switches. On a light fixture such as the one you've shown, the only exposed screws are separated from the conductors by a couple inches of insulating material and connected directly to the box, which should be grounded if it's metal. All of the metal light fixtures I've installed had ground terminals.

What about the metal screws used to mount it with ?

You can attach a ground wire to one of them if you feel the need...or ground the box, but as I said "...only exposed screws are separated from the conductors by a couple inches of insulating material."

Ok. Thanks everyone for the information. I learned something

If they’re going into a metal box, they pick up ground because the metal box is grounded, because Code requires you tie metal boxes to the ground wires.

If they’re going into a plastic box, they’re isolated.

If they’re going into a metal box, they pick up ground via the threads, because the metal box is grounded, because Code requires you tie metal boxes to the ground wires.
