Vase-wall around a hollow tube. Closed at the bottom and open at the top. Relate the form of specific structures to their function within this group.. Compare and contrast radial and bilateral symmetry.. Apply how the evolution of the segmented body led to increased motility. What should animals with radial symmetry be better able to do than those with bilateral symmetry?. move quickly in one direction. detect threats from above or below equally well. deal effectively with food distributed homogeneously in 360.
