Share to: bilateral symmetry is when you can divide something into to equal half's like if you cut a line through the middle of a circle you have 2 half's that are the same that is radi â¦ al symmetry.adial symmetry is every line or direction going towards a central axis in other words all directions pointing to the exact middle of the object. Hope this helps ^_^. P.S. If you don't believe me look it up.
Even hydras, which are primitive, radially symmetrical cnidarians, show some degree of cephalization. They have a âheadâ where their mouth, photoreceptive cells, and a concentration of neural cells are located. Flatworms (phylum Platyhelminthes) are the most primitive animals with bilateral symmetry.They also have a fairly advanced degree of cephalization, with sense organs (photosensory and chemosensory cells) and a brain concentrated at the anterior end.his process eventually produces a head region with sensory organs. Cephalization is intrinsically connected with a change in symmetry. It accompanied the move to bilateral symmetry made in flatworms, with ocelli and pinnae placed in the head region.
