Budding is a form of asexual reproduction. In single-celled organisms, such as budding yeast, it differs from binary fission in that the two resulting cells are not of equal size. Budding is also seen in multicellular organisms, including Hydras and sponges.

In virology, budding is a form of viral shedding by which enveloped viruses acquire their external envelope from the host cell membrane, which bulges outwards and encloses the virion.
In embryology, the term budding is applied to the process of embryo differentiation, in which old structures are formed in outgrowth from pre-existing parts.
In agriculture and horticulture, budding refers to grafting the bud of one plant onto another.
]] Budding is a way of asexual reproduction. With budding, a new organism grows on another one. It stays attached, while it grows. Only when it is fully grown does it detach from the parent organism. Since the reproduction is asexual, the newly created organism is a clone and is genetically identical to the parent organism.
Budding is very common in plants and fungi. Sometimes it can also be found with animals, for example with hydras or sponges.
