RADIAL SYMMETRY Meaning and
Definition
-
Radial symmetry is a term used in biology to describe a specific type of symmetry found in certain organisms. It refers to a body plan in which body parts are arranged around a central axis, resembling multiple mirror images that radiate outward from a central point. In other words, an organism with radial symmetry can be divided into identical halves by multiple planes passing through the center.
This pattern of symmetry is commonly observed in organisms such as jellyfish, sea anemones, and starfish. It is characterized by the arrangement of body parts, such as limbs or tentacles, around a central point, resulting in a circular or spherical form. This design allows for equal access to the environment in all directions.
One of the key advantages of radial symmetry is improved sensory perception. Organisms with this type of symmetry can detect changes in their surroundings equally from all sides, enabling them to respond effectively to stimuli and navigate their environment.
Radial symmetry is distinct from bilateral symmetry, which is characterized by the division of an organism into two identical halves along a single plane. While bilateral symmetry is more prevalent among higher organisms such as mammals and insects, radial symmetry is more common in simple multicellular and some single-celled organisms.
Overall, radial symmetry is an important adaptation in certain organisms, providing them with enhanced sensory capabilities and the ability to interact with their environment from all directions.

Etymology of RADIAL SYMMETRY
The word "radial" in "radial symmetry" is derived from the Latin word "radius", which means "spoke of a wheel" or "ray". The term "symmetry" comes from the Greek word "summetria", which means "proportion" or "regularity". Therefore, the etymology of "radial symmetry" suggests a symmetry that is characterized by an arrangement of parts around a central point, resembling the spokes of a wheel or rays.
