Question

Is hydra a unicellular organism or a multicellular organism?

Answer 1

Hydra:

1. Hydras are multicellular organisms.
2. Hydra is a genus of small freshwater organisms in the phylum Cnidaria and class Hydrozoa.
3. Hydra has a tubular, radially symmetric body that is held together by a simple adhesive foot called the basal disc.
4. The basal disc's adhesive properties are due to the production of a sticky fluid by gland cells in the basal disc.
5. A mouth opening at the free end of the body is surrounded by one to twelve thin, mobile tentacles covered in highly specialized stinging cells known as cnidocytes.
