Question

Express the process of budding in detail.

Answer 1

Hint: It is a method of asexual reproduction. It can occur from any point of body but can be restricted to a special area in some organisms. It can be external or internal. It can be symmetrical or asymmetrical. Hydra and yeast undergo this process.

Complete answer:
Budding is a method of asexual reproduction in which a new organism develop as an outgrowth or bud from the parent itself by cell division at any point on the body. Bud is a small bulb like projection outgrowing from the parent body. The newborns are identical to the parents except in case of mutations.
In the case of hydra, it uses regenerative cells for reproduction.
When these buds fully mature on the parent body, they detach themselves and become independent individuals.
Budding can be internal or external.
The bud formation on the parent itself is external budding. It is seen in hydra and yeast.
Internal budding is division of the parent itself into two or multiple daughter cells. It is seen in toxoplasma gondii. These buds can be symmetrical or asymmetrical. Asymmetrical budding is seen in saccharomyces cerevisiae (a kind of yeast used in brewing and baking). In this case the daughter is smaller than the parent.
Budding can also be seen in multicellular animals such as corals, sponges etc.
