EVERYDAY SCIENCE

Detailed explanation-1: -When any plane passing through the central axis of the body divides the organism into two identical halves, it is called radial symmetry . Phylum Coelenterata, Echinodermata and Ctenophora are exhibit radial symmetry.

Detailed explanation-2: -radial symmetry. noun. : plant and animal symmetry in which similar parts are arranged in a balanced way around the center of the body compare bilateral symmetry.

Detailed explanation-3: -Radial symmetry is found in the cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars).

Detailed explanation-4: -For example, pies, snowflakes, and starfish are radially symmetric because they have many different lines of symmetry (dividing them into matching halves) and the lines cross one another at the center.

Detailed explanation-5: -Radial Symmetry This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies).
