Collar cells Explanation: Porifera organisms are attached to the substrate. They do not show locomotion. To collect and capture food, they must generate a current in the water. They possess characteristic collar cells throughout their bodies for this reason. Germ cells and ectodermal cells are present in all other phyla. Cnidoblasts are a characteristic feature of coelenterates.
