Budding is an asexual mode of reproducing new organisms. In this process, a new organism is developed from a small part of the parent’s body. A bud which is formed detaches to develop into a new organism. The newly developed organism remains attached as it grows further. It is separated from the parent organism when it gets matured by leaving scar tissues behind. As this is an asexual reproduction, the newly developed organism is a replica of the parent and is genetically identical.
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.
For example- Both hydra and yeast reproduce by the process of Budding.
Budding in Hydra
Hydra is exclusively a freshwater organism having different species. It is very small, just a half centimeter long. It is a cnidarian having a tubular body which is composed of a head, distal end and a foot at the end.
Budding in hydra involves a small bud which is developed from its parent hydra through the repeated mitotic division of its cells. The small bud then receives its nutrition from the parent hydra and grows healthy. Growth starts by developing small tentacles and the mouth. Finally, the small newly produced hydra gets separate from its parent hydra and becomes an independent organism.
Budding in yeast
Yeasts are nongreen, eukaryotic, single-celled micro-organisms belonging to the kingdom fungus. They are generally larger than the bacteria and they typically measure 3-4 µm in diameter. Yeast cells reproduce asexually by an asymmetric division process called budding.
In yeast, budding usually occurs during the abundant supply of nutrition. In this process of reproduction, a small bud arises as an outgrowth of the parent body. Later the nucleus of the parent yeast is separated into two parts and one of the nuclei shifts into the bud. The newly created bud divides and grows into a new cell.
