What is hydra class8?
In hydra, first a small outgrowth called bud is formed on the side of its body by the repeated divisions of its cells. This bud then grows gradually to form a small hydra by developing a mouth and tentacles. And finally the tiny new hydra detaches itself from the body of parent hydra and lives as a separate organism.
