Share. By Jennifer Kennedy. Definition: Radial symmetry is the regular arrangement of body parts around a central axis. When an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.Examples: Sea urchins have radial symmetry.hen an organism is radially symmetrical, you could cut from one side of the organism through the center, to the other side, anywhere on the organism, and this cut would produce two equal halves.
Another common type of symmetry is radial symmetry, in which an organism can be divided equally about a central point, much like a pie cut into equal parts.xamples. In the plant kingdom, it is common to see radial symmetry in flowers, though the rest of the plant may exhibit other symmetry, or no symmetry at all. Flower petals tend to extend from the central axis into a radial pattern, and fruits frequently have radial symmetry.
