Question

Fill in the blanks________ type of reproduction occurs in Hydra
(a) Binary fission
(b) Multiple fission
(c) Budding
(d) Fragmentation

Answer 1

Hint: A type of asexual reproduction found in the members of the phylum coelenterate. The offspring develops through the repeated mitotic division as the new cell grows out of the parental cell. The new cell can now grow on their own into a new hydra.

Complete answer:
Budding occurs in Hydra. In this process, the parent cell remains (or not destroyed) and a new daughter cell is formed. The hydra uses the regenerative cells to produce in this manner. The new hydra grows in the form of a bud and stays attached to the parental body while it grows. In Hydra, the budding occurs at a specific point only. The small bud then receives its nutrition from the parent hydra, which helps it to grow. Development begins with the advancement of little appendages and the mouth until the recently delivered hydra gets isolated from its parent hydra and turns into a free creature. Since it is an asexual type of reproduction, the new organism is genetically similar to the parent hydra.
- Budding is also common in sponges.
- In many species, the buds can emerge at any point from the body, while in some it is restricted to a specialized area.
- In many species, the new individual separates to exist separately from the parent, and in some the buds may remain attached, forming aggregates or colonies.
- Coelenterates exhibit asexual reproduction by budding and sexual reproduction by medusa.
So, the correct answer is, ‘Budding.’

Note:Budding is most commonly associated in both multicellular and unicellular organisms. Some animal species that reproduce by the process of budding are bacteria, yeast, Jellyfish, corals, flatworms, and sea anemones.
