What is the level of organisation in hydra?
Hydra exhibit tissue level organization, where cells are organized into tissues but lack specialized organ systems. They have two layers of cells, an outer epidermis and an inner gastrodermis, separated by a jelly-like substance called mesoglea.
How many cell layers does a hydra have?
A hydra typically has two cell layers: an outer layer of epithelial cells and an inner layer of gastrodermal cells. These layers are separated by a jelly-like extracellular matrix called the mesoglea.

Why hydra have no organs?
Hydra, a simple freshwater organism belonging to the phylum Cnidaria, lack complex organs because of their basic body plan and evolutionary adaptations. They have a simple tissue structure organized into two layers: the epidermis and gastrodermis, with a gelatinous mesoglea in between. This simplicity allows them to perform essential functions like digestion and movement without specialized organs. Instead, hydra rely on diffusion for gas exchange and nutrient absorption, which is efficient in their small, aquatic form.

What is the respiratory organ of hydra?
Hydra is a multicellular animal with tissue level of organization but has no organs. It has a large surface area in relation to its volume. Being diploblastic, it has two layers of cells in its body. As most of its cells are in direct contact with water, the ectodermal cells exchange gases with external water while endodermal cells with water that comes within the gastro-vascular cavity.
