Question

Difference between radial and biradial symmetry

Answer 1

biradial symmetry is a combination of radial and bilateral symmetry as in ctenophores the body components are arranged with similar parts on either side of the central axis and each of the four sites of the body is identical to opposite side but different to adjacent side
where as in radial symmetry the body is divided in two equal halves in any plane

Answer 2

let me tell you practically ....in by radial symmetry there are two planes which can divides the organism into two parts....simply u can slice them to get bilateral symmetry in two different way..
