Hydra reproduce by

Answer 1

Reproduction and life cycleWhen food is plentiful, many hydras reproduce asexual-reproductionby producing buddingin the body wall, which grow to be miniature adults and simply break away when they are mature. When conditions are harsh, often before winter or in poor feeding conditions, sexual-reproductionoccurs in some hydras. Swellings in the body wall develop into either a simple ovary or testes. The testes release free-swimming gametes into the water, and these can fertilise the egg in the ovary of another individual. The fertilized eggs secrete a tough outer coating, and, as the adult dies, these resting eggs fall to the bottom of the lake or pond to await better conditions, whereupon they hatch into miniature adults. Hydras are hermaphroditeand may produce both testes and an ovary at the same time.

Many members of the hydrozoa-1go through a body change from a polyp-2to an adult form called a medusa. However, all hydras remain as polyps throughout their lives.

Answer 2

Hydra reproduce asexually by budding. This involves the formation of a small outgrowth, or bud, on the body of the Hydra that eventually detaches to become a new individual.
