Budding is a form of asexual reproduction characterized by mitosis followed by unequal cytoplasmic division. Asexual reproduction is a form of reproduction for single-celled organisms such as bacteria, archaea, and protists. Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell for example is called a bud. The new organism remains attached as it grows, separating from the parent organism only when it is fully grown.
