Detailed explanation-1: -Sponges re produce both asexually and sexually. Asexual reproduction occurs by budding. Figure below shows the sponge life cycle when sexual reproduction is involved. Adult sponges produce eggs and sperm.

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: -Sponges belong to the phylum Porifera. They reproduce by sexual and asexual mode. The asexual mode involves budding.

Detailed explanation-4: -By means of external budding or gemmules, asexual reproduction in sponges takes place.

Detailed explanation-5: -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).
