Certain animals have their body parts arranged around a central point. A starfish is a good example of this, which is known as radial symmetry.
radially symmetric
Radial Symetry :)

Radial Symmetry .
polyp
A group of primitive aquatic animals that include jellyfish, corals, and sea anemones. Colenterates are sessile (sedentary) and exhibit symmetry. Their body parts are symmetrically arranged around a central point.
radial symmetry which means that all the parts of the body are arranged around a central axis in such a way that any plane passing through the central axis divides the animal in halves that are almost mirror image of each other
A radial body plan. Starfish and jellies are example of organisms with a radial morphology.
how are the body parts of an organism arranged
In spherical symmetry, body parts radiate out from a central point; an infinite number of planes passing through the central point can divide a spherically symmetrical organism into similar halves. In Radial symmetry, body parts are arranged around one main axis at the body's center.
One stack is a granum. Two or more stacks are called grana.
