Budding is a common process in plants and fungi. It also occurs in certain animals, particularly the Hydra (sponges). In sponges, the outgrowth (bud) stays attached permanently while in fungi the bud stays for a while, and then detaches to grow fully as a new individual. Budding is a form of asexual reproduction since the process results in the formation of new individual but is a clone of the primary organism.

In viruses, budding is their means to leave the cell while not causing lysis to their host cell. In this way, the remaining viruses can still propagate within the host cell.

Word origin: bud(d) + -ing
