HEY!!!!!!
They have different physical and electrical properties. In most transistors, emitter is heavily doped. Its job is to emit or inject electrons into the base. These bases are lightly doped and very thin, it passes most of the emitter-injected electrons on to the collector.

FURTHER when emitter is:-
Emitter is heavily doped to provide large no. of majority charge carriers & base and collector are lightly doped to accept these charge charge carriers from emitter.

so emitter has more current than collector & base
