Role of symmetry is very crucial to explain the various properties and behaviour of the elementary particles. Every symmetry are always associated with corresponding conservation law and it can be either discrete or continuous in nature. The symmetries of the standard model associated with the electromagnetic interaction, weak and strong force are described by the groups U(1), SU(2) and SU(3). Fundamental aspect for some of the symmetry like as permutation symmetry, continuous space-time symmetry, discrete symmetry are elaborated here. higher level of symmetry flavour symmetry, super symmetry and SU(5) symmetry for unification is also discuss here. Various cause of symmetry breaking is discussed here. Consequences of the existence of symmetry is that a corresponding conservation law like as conservation of charge, linear momentum, angular momentum, energy, baryon number, lepton number, parity etc. In this research paper elaboration of various conservation law and its consequences is also done in modern context.
