The parts individually of a motor may not be as hard to retrieve, but you would have to put them together.
The oxidizer provides oxygen to drive the combustion chemical reaction. (Combustion, an oxidation reaction, is the combination of oxygen with some other substance.)
The fuel is the substance with actually "burns" (is oxidized). This reaction between the oxidizer and fuel generates gas and heat, which provides the motive power for the rocket.
The case keeps the motor together and under the correct pressure. Without pressure, the reaction will proceed too slowly and the fuel will burn without producing enough gas for efficient thrust. If the pressure gets too high, the motor will explode (CATO).
The nozzle directs the gas formed by the reaction out the back of the rocket. The nozzle is formed such that the gasses are accelerated as they pass through the nozzle and provide efficient thrust.
