Sponges exhibits Cellular level of organization. 
Coelenterate shows tissue level of organization.
organ level is exhibited by members of Platyhelminthes and
other higher phyla.

In Open type type of circulatory system the blood is pumped
out of the heart and the cells and tissues are directly bathed
in it.
In closed type in which the blood is circulated through a
series of vessels of varying diameters (arteries, veins and
capillaries).

When any plane passing through the central axis of the body 
divides the organism into identical halves, it is
calledRadialsymmetry and when only one plane can divide
body into identical left and right halves, it is
called bilateral symmetry.
