The correct answer is Hydra.

Key Points

  • Hydras are multicellular organisms that inhabit fresh water.
  • They are members of the phylum Cnidaria and possess radial symmetry.
  • They are categorised as being diploblastic.
  • Tentacles with cnidocytes encircle the mouth.
  • Within these cnidocytes are nematocysts, or stinging capsules.
  • They both engage in sexual reproduction and asexual reproduction.
  • The asexual reproductive mechanism takes the form of budding.
  • Hydra can regenerate quickly.

Additional Information

  • Reproduction is the biological process by which a new form of life is produced from pre-existing similar life.
  • Reproduction helps in the continuation of the species.
  • There are two main modes of reproduction - Asexual and Sexual Reproduction.
  • Asexual reproduction:
    • Asexual reproduction does not involve the fusion of gametes.
    • The progeny formed through asexual reproduction are genetically identical to their parents.
    • Fragmentation, budding, binary fission, gemmule formation, etc. are some of the methods of asexual reproduction.
    • Hydra, yeast, and sea stars all reproduce asexually.
  • Sexual reproduction:
    • Sexual reproduction involves the fusion of male and female gametes (haploid) to form the zygote (diploid).
    • Sexual reproduction involves two major events - Meiosis and the Fusion of gametes.
    • The progeny formed through sexual reproduction are genetically dissimilar. 
    • Mammals, amphibians, angiosperms, etc. show sexual reproduction.
