Features of the structure of the reproductive cell in hydra.

The germ cells in hydra arise from repeated divisions of interstitial cells in some limited areas of the hydra’s body during the summer. They form gonads, which then differentiate into either testes or ovaries.

A hydra can reproduce itself by creating another, smaller hydra. They do this by gradually increasing a little hydra on their side using mitosis. But hydras, like some unicellular eukaryotes, can also reproduce using meiosis. Usually hydras are neither male nor female, but when they are about to reproduce using meiosis, one hydra grows testes to make sperm, and another hydra grows ovaries to create egg cells.
