The helicopter main rotor blades have an airfoil shape like an airplanes wing. The entire blade can also be angled by the pilot,through the rotor head. This angle makes it fly or lift.
Planes have large wings, Helicopters have rotors

Its Spins The Helicopters Wings
It's called a propeller.
Helicopters don't use fixed wings
Humans. We don't have wings, but we build airplanes and helicopters.
A helicopter is an aircraft without fixed wings. Helicopters can also be known as rotorcraft.
According to NASA, future helicopters may be probably made of shape-changing materials.
Yes, probably, they do have small wings and free auto-rotation.
They derive lift and propulsion from the rotor
No, airplanes need wings for lift. - Now having said that, aircraft can fly without wings, as they include helicopters, dirigibles and balloons which have alternate ways of gaining lift.
