Question

Quizplus · Accepted Answer

The two layers of tissue in a hydra are the epidermis, which covers and protects the organism, and the gastrodermis where cells that complete digestion are found. The gastrodermis also contains specialized cells called cnidocytes used for capturing prey. The other options are incorrect because they either mix up the functions of the two layers or include structures (such as nephridia and flame cells) that are not present in a hydra.
