Definition

adjective

Pertaining to, characterized by, or exhibiting symmetry


Supplement

In biology, symmetry refers to the proportionality of one side to the other side(s) in a sagittal plane or around an axis. A body plan, for instance, is described to be symmetrical if the parts on one side is (more or less) the same as those of another in terms of form, number, arrangement, and/or position.

Most flowering plants show symmetry. Their flowers may be radially symmetrical or bilaterally symmetrical. Radially symmetrical flowers have floral parts that are of the same form, components, and size around an axis. Bilaterally symmetrical flowers are those in which the left and the right sides of a sagittal plane are mirror images.
