Explain budding process in yeast.

Budding in yeast:

Budding is a type of asexual reproduction seen in yeast, hydra etc. It is the process of development of a smaller bud from an adult organism directly without involvement of any gametes.

A soft zone appears in the cell wall of vegetative cells. Small buds will bulge out from this zone. At this stage, the nucleus of the cell undergoes a mitotic division. One of the daughter nuclei will be pushed into the bud. A constriction is formed between the vegetative structures and the bud, which can grow into new yeast cells. The bud finally separates from the parent organism and develops into an adult.
