What are regenerative cells used by Hydra for?
Hydra uses regenerative cells for reproduction by sexual reproduction.
Hydra uses regenerative cells for reproduction by spore formation.
Hydra uses regenerative cells for reproduction by fragmentation.
Hydra uses regenerative cells for reproduction by budding.
Hydra uses regenerative cells for reproduction by budding.
Hydra utilizes specialized regenerative cells, particularly interstitial cells, to reproduce asexually through a process known as budding. During budding, a small outgrowth or bud develops on the body wall of the parent Hydra due to repeated cell division, eventually growing tentacles and detaching to live as an independent organism.

During budding, a small outgrowth or bud develops on the body wall of the parent Hydra due to repeated cell division, eventually growing tentacles and detaching to live as an independent organism.
In evolutionary biology, Hydra belongs to the Phylum Cnidaria (Coelenterata) and Class Hydrozoa, notable for exhibiting radial symmetry and possessing remarkable powers of cellular regeneration mediated by totipotent interstitial cells.
Hydra primarily reproduces asexually through budding under favorable environmental conditions.
Regenerative cells (interstitial cells) undergo repeated mitotic divisions to form the bud.
Sexual reproduction in Hydra typically occurs under adverse environmental conditions involving testes and ovaries.
Option A is incorrect because sexual reproduction in Hydra involves gamete fusion, not specialized regenerative cells forming buds.
Option B is incorrect because spore formation is typical of fungi, algae, and some bacteria, not Hydra.
Option C is incorrect because fragmentation involves accidental breaking of the organism, whereas budding is a planned outgrowth process.
Hydra exhibits high morphallactic and epimorphic regeneration capacity due to continuously dividing stem cells.
D is correct тАФ Hydra uses regenerative cells for reproduction by budding.
In general science questions for competitive exams, always distinguish between budding (seen in Yeast and Hydra), binary fission (Amoeba), and fragmentation (Spirogyra).
