Question

explain the body symmetry

Answer 1

Symmetry in biology is the balanced distribution of duplicate body parts or shapes within the body of an organism. In nature and biology, symmetry is always approximate. For example, plant leaves – while considered symmetrical – rarely match up exactly when folded in half. Symmetry creates a class ofpatterns in nature, where the near-repetition of the pattern element is by reflection or rotation.

Answer 2

Specifically, symmetry refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis. With the exception of radial symmetry, external form has little relation to internal anatomy, since animals of very different anatomical construction may have the same type of symmetry.
