Question
Members of the phylum Cnidaria show all of the following characteristics EXCEPTQuestion 6Select one:a.Polyp stageb.Cnidocytesc.Pseudocoelomd.Medusa stagee.Epidermis and Gastrodermis
Solution
The correct answer is c. Pseudocoelom. Members of the phylum Cnidaria, which includes organisms like jellyfish and sea anemones, do not have a pseudocoelom. A pseudocoelom is a type of body cavity found in some animals, but Cnidarians have a simpler structure with only one internal cavity, the gastrovascular cavity. They do have a polyp stage and a medusa stage in their life cycle, they possess cnidocytes (specialized cells for capturing prey), and they have two main tissue layers, the epidermis and gastrodermis.
