A dormant mass of amoebocytes surrounded by protective layers of spicules is known as a gemmule. Gemmules are a form of asexual reproduction in sponges and can survive harsh environmental conditions until they are ready to develop into a new sponge.
The buds formed inside a sponge during asexual reproduction are called gemmules. These structures contain a cluster of cells surrounded by a protective layer and can detach from the sponge to form a new individual under favorable conditions.
They are examples of organelles
examples of staminate flowers
There are four examples of civilization. The four examples are tsunami, earthquakes, massive fire and climate change.
sexual for the win i love being sexual
They are used as reproductive agents in asexual reproduction.
gemmules
its because the gemmules are like the little packages that hold the start of another sponge, so even if the sponge doesnt survive, the gemmule will, and then when conditions get better the gemmule will make another sponge.

Gemmules are internal buds found in sponges that are the result of asexual reproduction, and are a response to a hostile environment.They are resistant to desiccation (drying out), freezing, and anoxia (lack of oxygen) and can lie around for long periods of time. They would be good for the distribution of a population of sponges.
Of the choices choanocytes, medusa, spicules, or gemmules, Medusa is the option that is not associated with sponges.

Spongilla is a genus of freshwater sponge in the family Spongillidae. They are found in lakes and slow streams. Sponges of the genus Spongilla attach themselves to rocks and logs and filter the water for various small aquatic organisms such as protozoa, bacteria, and other free-floating pond life. Unlike marine sponges, fresh-water sponges are exposed to far more adverse and variable environmental conditions, and therefore they have developed gemmules as a means of dormancy. When exposed to excessively cold or otherwise harsh situations, the sponges form these gemmules, which are highly resistant "buds" that can live dormantly after the mother sponge has died. When conditions improve, the gemmules will "germinate" and a new sponge is born.

Sea sponges have no courtship. Most can't even move to new locations. They reproduce by either budding or produce gemmules (replications of themselves that are like "time-release" capsules).
