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.
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.
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.
Oh, dude, let me break it down for you. So, gemmules are like these little sponge babies that can survive tough conditions, but larvae are like the cool kids who can swim around and find new homes. So, if you want your sponge population to spread far and wide, larvae are the way to go. Gemmules are more like the backup plan for when things get rough.
Depending on the type of sponge, they can reproduce either sexually or asexually. Sexual reproduction of a sponge is when a male sponge releases a large cloud of sperm in the water and when it passes by a female sponge of the same species it passes through special cells called archaeocytes. This funnels the sperm toward the egg cells already in the female sponge to create the larvae. Depending on the type of sponge, the female will either release the larvae soon afterward or store them and release them later. Asexual reproduction of a sponge happens when each individual sponge produces buds, or packets of several cells inside a protective covering which later develops into adult sponges.
gemmules
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.
asexual reproduction its when a piece of a sponge falls of and can grow to a replica of that sponge.. 7th grade science easy stuff!
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).
1.most sponges are hermaphroditic, having the ability to act as both males and females. when acting like a male, the sponge releases a substance called sperm n the water. when a sponge of the same species catches a the sperm, it will form the larvae witch will develop in the sponge after a while. when the larvae are ready, the sponge will release them into the water. that's one of the ways! love, science lover!
Sponges can reproduce sexually or asexually. They can reproduce through producing eggs and sperm that are released into the water where they can combine to form larvae. Asexual reproduction can occur through budding, fragmentation, or producing gemmules.
