Question

Differentiate between the ‘Budding in the Hydra’ and ‘Binary fission of Amoeba’?

Answer 1

The species reproduce asexually in one of the above processes by using regenerative cells for reproduction, while in another method, asexual reproduction by splitting the body into two separate bodies.

Complete answer:
Budding in the Hydra
Budding is a form of asexual reproduction where, due to cell division at a specific site, a new organism emerges from an outgrowth or bud. The little bulb-like projection that comes out of the yeast cell is called a bud. Since reproduction is asexual, the newly formed organism is a duplicate and the genetically identical parent organism except for mutation occurs within an organism.

Organisms like hydra use regenerative cells to replicate during the budding process. In hydra, the outgrowth of a bud occurs as a result of repeated cell division at one particular site. These buds grow into tiny individuals and split from the parent body when fully grown, and become new independent individuals. Cnidarians such as jellyfish, bacteria, yeast, sea corals, flatworms, and sea anemones are some animal species that reproduce by budding.

Binary fission of Amoeba
Binary fission is typically observed in prokaryotes and few single-celled eukaryotes as a form of asexual reproduction. A division of the parent cell into two new daughter cells occurs in this asexual reproduction process. This process happens with the parent's genetic matter being separated and duplicated into two parts, where each daughter cell receives one copy of its parent DNA.

It is a main reproductive mechanism among prokaryotic species. Binary fission occurs within the cell without the development of any spindle apparatus. The single DNA molecule starts replication in this process and then binds each copy to different parts of the cell membrane. When the cell begins to pull apart, the original (actual) and replicated chromosomes get separated. Such Prokaryotes as E. coli bacteria, archaea, and eukaryotes such as euglena replicate by binary fission.

Note: Budding is a form of asexual reproduction found most commonly in multicellular and unicellular animals. Binary fission is a kind of cell division process into eukaryotes and It is a type of asexual reproduction in prokaryotes.
