Hydra is a small, fresh water organism that reproduces asexually via the process of budding.


In hydra, when enough nutrition is available, a small outgrowth is formed. This out growth is known as a bud. This bud is formed as a result of repeated mitotic division.


The bud gradually grows and forms a small Hydra. It develops a mouth and tentacles.


This newly formed Hydra then detaches itself from the parent Hydra and continues living as a separate, free organism.
