Question

Quizplus · Accepted Answer

Bilaterians are characterized by having mirror symmetry, which allows for a distinct head and tail and only one plane of symmetry. This symmetry is important for developing specialized body parts and movement in a coordinated manner. Radial symmetry (A) is found in animals such as jellyfish and starfish, and circular symmetry (C) does not exist in biological organisms. No symmetry (B) would not allow for the development of distinct body parts and is not characteristic of bilaterians.
