Hydra has two main body layers, which makes it "diploblastic". The layers are separated by mesoglea, a gel-like substance. The outer layer is the epidermis, and the inner layer is called the gastrodermis, because it lines the stomach. The cells making up these two body layers are relatively simple.

WebThe structure of a hydra is fairly simple (Fig. 1 ). It consists of a single axis with radial symmetry, which contains a head, body column, and foot along the axis. The head consist of two parts: the hypostome in the apex, and the tentacle zone from which the tentacles emerge in the basal part of the head. WebThe adult Hydra polyp continually renews all of its cells using three separate stem cell populations, but the genetic pathways enabling this homeostatic tissue maintenance are not well understood.
