Question

Define bilateral symmetry. Which animal shows radial symmetry?

Answer 1

bilateral symmetry

n. Symmetrical arrangement, as of an organism or a body part, along a central axis, so that the body is divided into equivalent right and left halves by only one plane.

animals are-echinoderms, such as sea stars, urchins, and sea cucumbers. Sea stars have what is called a pentamerous radial symmetry, meaning it is divided in five ways around its central point.

Bilateral symmetry:

When the body can be divided into identical left and right halves in only one plane, it is called bilateral symmetry and the animals possessing this type of symmetry are called bilaterally symmetric.

Radial symmetry:

When any plane passing through the central axis of the body divides the organism into two identical halves, it is called radial symmetry and the organisms possessing it are called radially symmetric.
examples:
• some sponges,
• coelenterates,
• Ctenophores.
