Final answer:
Animals, except for sponges, typically have symmetrical body plans with specific developmental characteristics important for classification. The body's 'planes' mentioned in the question seem to refer to these symmetrical body plans rather than botanical subjects.
Step-by-step explanation:
Similarities between Animal Body Plans:
The body plans of animals are symmetrical and share developmental characteristics that contribute to their classification. All animals except sponges generally display a symmetrical distribution of body parts along at least one major body axis.
While the question mentions the body's 'plants,' it seems to be referring to 'planes,' which suggests it is asking about the body plans. Considering the provided options and reference information, the body's planes are not segmented into regions or looked at exclusively from a physiological standpoint, nor do they bisection the body into two separate parts or have similar names. Instead, their symmetry and developmental pathway characteristics are crucial classification aspects.
