Detailed explanation-1: -Budding is a second method of asexual reproduction in sponges. Porifera members can grow an external bud which eventually breaks off and grows into a clone of the original. Finally, when conditions are not favorable for other methods, sponges can reproduce asexually through gemmules.

Detailed explanation-2: -Sponges can reproduce either asexually or sexually. Asexually reproduction (without eggs and sperm) often occurs by budding, similar to growing a new branch on a tree. Cells on the side or base of the parent begin to bulge out and form a new organism.

Detailed explanation-3: -Asexual reproduction also occurs in sponges in various ways; the best known method is called gemmulation. Gemmulation begins when aggregates of cells, mostly archaeocytes, which, when they become laden with reserve food granules become isolated at the surface of a sponge and surrounded by a protective covering.

Detailed explanation-4: -The typical means of asexual reproduction is either fragmentation (where a piece of the sponge breaks off, settles on a new substrate, and develops into a new individual) or budding (a genetically-identical outgrowth from the parent eventually detaches or remains attached to form a colony).

Detailed explanation-5: -Budding is a type of asexual reproduction, which is most commonly associated in both multicellular and unicellular organisms. Bacteria, yeast, corals, flatworms, Jellyfish and sea anemones are some animal species which reproduce through budding.
