Detailed explanation-1: -For reproduction, Hydra uses regenerative cells where a bud expands as an outgrowth because of repeated cell division at one specific location. These buds then developed into new small individuals which when completely matured, detach from the parent body.

Detailed explanation-2: -Hydra reproduces by the mechanism of budding and fragmentation. It cannot undergo multiple fission since that is not a viable option for a multicellular organism such as Hydra. Spore formation is an asexual method of reproduction, mostly seen in fungi.

Detailed explanation-3: -The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent.

Detailed explanation-4: -Budding is a type of asexual reproduction. In hydra, a bud develops as an outgrowth due to repeated cell division. Now the nutrition for bud growth is provided by the parent hydra. The development showed by bud starts to develop small tentacles and a mouth.
