Definition and Meaning

Budding can be defined as a type of asexual reproduction wherein a new organism develops from an outgrowth or bud due to cell division at one site.
It belongs to Animalia kingdom, Cnidaria Phylum, and Hydrozoa class.
A new organism is developed from a small part of the parent՚s body.
It also means the process of bud formation in both unicellular (e. g. budding bacteria and yeast cells) and multicellular organisms (e. g. plants and sponges) .
By leaving scar tissues behind, the newly developed organism s separated from the parent organism.
- The newly developed organism is a replica of the parent.
- The newly developed organism is also genetically identical.

It is most associated with multicellular as well as unicellular organisms.
Some of the animal species which reproduce through budding are Bacteria, yeast, corals, flatworms, Jellyfish, and sea anemones.

Hydra is a small freshwater organism having different species.
The tubular body is composed of a head, distal end, and a foot at the end.
The budding process involves a small bud.
This small bud is developed from its parent hydra through the repeated mitotic division of its cells.
Nutrition is received from the parent hydra by the small bud.
By developing small tentacles and the mouth growth starts.
At last the small newly produced hydra gets separate from its parent hydra and becomes an independent organism.

Yeast cells reproduce asexually by an asymmetric division.
They are eukaryotic belonging to the fungi kingdom.
Yeasts belong to the fungus kingdom and are non-green, eukaryotic, single-celled microorganisms.
These are larger than the bacteria with typical measurement of 3 - 4 µm in diameter.
During the abundant supply of nutrition, budding usually occurs.
Due to an outgrowth of the parent body, small bud arises.
The nucleus of the parent yeast is separated into two parts.
- One of the nuclei shifts into the bud.
It is this newly created bud that divides and grows into a new cell.

Q 1. List out some examples of budding.

Answer:

Some examples of budding are Bacteria, yeast, corals, flatworms, Jellyfish, and sea anemones.

Q 2. How does the process of budding occur in yeast?

Answer:

The budding process in yeast occurs is asexual.
A small protuberance on the parent cell is produced first which grows into a full size and a bud is formed.
The parent cell nucleus splits into a daughter nucleus and migrates into the daughter cell.

Q 3. Hydra belongs to which kingdom, phylum, and class?

Answer:

Hydra belongs to Animalia Kingdom, Cnidaria Phylum and Hydrozoa Class.

Q 4. Yeasts belong to which kingdom?

Answer:

Yeasts belong to the fungi kingdom.
