GENERAL HISTOLOGY

Detailed explanation-1: -Hint: When identical parts are arranged in a circular manner around the central point, the symmetry is called radial symmetry. Dividing an organism by an imaginary plane through the central axis yields identical parts.

Detailed explanation-2: -Radial symmetry is when all segments are equal that radiate from a point. A ball or a circle has radial symmetry.

Detailed explanation-3: -Radial symmetry is found in the cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars).

Detailed explanation-4: -When any plane passing through the central axis divides the body of an organism into two equal halves then the symmetry is Radial symmetry.

Detailed explanation-5: -Organisms with radial symmetry show a repeating pattern around a central axis such that they can be separated into several identical pieces when cut through the central point, much like pieces of a pie.
