What are the differences between a propeller and a turbine in terms of their design, function, and applications?

Propellers are typically used in smaller aircraft and boats, while turbines are used in larger aircraft and power plants. Propellers have blades that rotate around a central axis to generate thrust, while turbines have blades that are turned by a fluid or gas to generate power. Turbines are more efficient at higher speeds and altitudes, while propellers are better suited for lower speeds and altitudes.
