TestHub · Accepted Answer

Actinomorphic flowers have a symmetry similar to radial symmetry in animals. The type of symmetry in which any plane passing through the central axis of the body divides the organism into two identical halves is known as radial symmetry. It is shown by organisms belonging to Phyla Ctenophora, Coelenterata and Echinodermata. Adamsia and Gorgonia belong to the phylum Coelenterata. Pleuroblanchia belongs to the phylum Ctenophora. Cucumaria and Ophiura belong to the phylum Echinodermata. Hence, these 5 organisms show radial symmetry.
