asymmetrical- sponges are asymmetrical.i.e. any plane that passes through the center does not divide them into equal halves.
radial symmetry- the plane passing through the central axis of the body divides the organism into two identical halves, it is called radial symmetry.coelentrata,ctenophora and echinodermata have this kind of body plan.
bilateral symmetry-the body can be divided into identical left and right halves in only plane, exhibit bilateral symmetry.

BILATERAL SYMMETRY
