How would you describe cnidarian tissue organization?

• A. Diploblastic With True Tissues
• B. Triploblastic With No True Tissues
• C. Pseudotissue Organization
• D. No Tissues

Answer: (A)

Cnidarians have tissue-level organization with two germ layers, so they are diploblastic. Their bodies consist of an outer epidermis and an inner gastrodermis, with a gel-like mesoglea between them. This arrangement means their cells are organized into true tissues, even though they lack a third germ layer (mesoderm) and therefore don’t form complex organs like many other animals. The two-tissue-layer setup gives cnidarians the ability to line their body cavity and carry out functions in a coordinated way, even with simple body plans. The alternatives would imply three germ layers or no true tissues, which doesn’t describe cnidarians.
