Bilateral Symmetry Definition

In terms of bodily parts or appearance, a type of symmetry in which the opposite sides of a midline are identical.

Symmetry is a biological trait characterised by uniformity in components in a plane or around an axis in certain organisms.

On both sides of the axis, a symmetrical creature (one having symmetry) would have a balanced distribution of duplicate components.

It is possible that it is not an identical replica, but rather a close match.

Bilateral symmetry is an example of symmetry in organisms.

Bilateral symmetry is a type of symmetry in which both sides are the same.

In a sagittal plane, the exterior appearance is the same on the left and right sides (such as the body plan of most animals, including humans).

The body plan of an organism with bilateral symmetry is divisible into equal mirror halves in the sagittal plane.

Internal bodily components, such as organs, are not always symmetrical.

Bilateria is a taxonomic group that includes creatures that have bilateral symmetry.

These creatures (also known as bilaterians) have left and right sides, which distinguishes them from species with various types of symmetry (such as radial symmetry) and those without symmetry (asymmetry).

The orchid and pea families are examples of bilateral symmetry in the plant kingdom.
