<h3>What is an organism's body plan?</h3>
An animal group, such as a phylum, can be recognized by its body plan, which is a collection of morphological and developmental traits.
Whether they are in the embryonic, larval, or adult stages of development, all members of a certain group have the same body design at some point.
True animals can be broadly categorized into three groups based on the symmetry of their body plans: radially symmetrical, bilaterally symmetrical, and asymmetrical, at the most fundamental level of classification.
