Spherical Symmetry. The body has the shape of a sphere and the parts are arranged concentrically around or radiate from the center of the sphere. Such an animal has no ends or sides, and any plane....Radial Symmetry. Radialsymmetry is a symmetry in which the sides exhibit correspondence or regularity of parts around a central axis. It is lacking the left and right sides. It is in contrast to bi...Biradial Symmetry. Biradial symmetry is found in organisms that show morphological features (internal or external) of both bilateral and radial symmetry. e.g, sea anemones. The animals which show r...Bilateral Symmetry. Symmetry in which similar anatomical parts are arranged on opposite sides of a median axis so that only one plane can divide the individual into essentially identical halves. Bi...The equal distribution of body parts and sense organs makes them better able to react to environmental stimuli coming from all around their bodies.As the shapes of organs and cells are strictly connected to their activities and functions, symmetry is an important matter also at those scales.Symmetry creates balance, and balance in design creates harmony, order, and aesthetically pleasing results.Plants exhibit both radial symmetry and bilateral symmetry, often at the same time. In flowers, it has a lot to do with pollination strategy. A sunflower head has radial symmetry, allowing small insects to land on top, while a snapdragon flower has bilateral symmetry, inviting large bees to enter from the side. In biology, symmetry is approximate. ...

At a very basic level of classification, true animals can be largely divided into three groups based on the type of symmetry of their body plan: radially symmetrical, bilaterally symmetrical, and asymmetrical. Asymmetry is seen in two modern clades, the Parazoa (Figure 27.7 a) and Placozoa.
