Hydra is a genus of small, fresh-water organisms that are classified under the phylum Cnidaria.
Metagenesis is the process through which one generation of animals and plants reproduces asexually before giving birth to a sexually reproducing generation.
Hydra reproduces only through budding, which is an asexual way of reproduction.
Metagenesis is not feasible in Hydra since there is no sexual reproduction.
