What is the respiration process of a hydra
Answers
Answer:
Without circulatory, respiratory, or excretory systems, the hydra's cells depend on simple diffusion to deliver respiratory gases and ingested matter for nutrition, and these freshwater coelenterates have no functional need for blood. Asexual reproduction by the hydra occurs through budding, or regeneration.
Answer:
In a phylum dominated by marine species as diverse as the jellyfishes and corals, the hydra (class Hydrazoa) are among the few commonly observed coelenterates in freshwater ecosystems. Skipping the medusa stage typical of the jellyfish, the stalked and tentacled invertebrate polyps can reproduce sexually or asexually. They follow the basic coelenterate radially symmetric body plan of two cell layers without a true body gut, having instead a gastrovascular cavity, with the mouth as a single opening.
