How is freshwater hydra used?

Hydra, also known as a freshwater polyp, belongs to the class of coelenterates. Tentacles extend from the body of this microorganism, which help it to grasp food and move around. Its main feature is its ability to regenerate. Intermediate cells located on the surface of the hydra’s body are capable of transformation into any other type of cell. Even if you cut this organism in half, it will grow back the missing body part. These features are very important for the development of science and medicine, therefore, hydra is actively used by scientists to study the processes of regeneration, which can be applied to treat people.
