What are the Characteristics of Gemmules?
Gemmules lack a lot of structure and definition, but they have the following qualities:
- Gemmules are highly resistent structures that can withstand extreme conditions like dessications, freezing, etc.
- They may also survive severe oxygen shortages.
- Gemmules resemble bacterial endospores and usuasly act as survival structures
- They are spherical and lie in cluster.
- They are capable of floating and have a peumatic layer that provide buoancy.
- They are composed of germinative cells called archaeocytes .
- A thin coating of spicules covers them, providing support and discouraging predators.

Gemmule – Formation, Structure and Role in Sponge Reproduction
Gemmules are the asexual reproductive structures found in some freshwater and marine sponge species. The gemmules in sponges are produced in adverse weather circumstances, including drought or low temperatures. The gemmules play a role in giving sponges the ability to tolerate harsh environmental conditions. In this article, we will study the gemmules in sponges, their structure, characteristics, and their advantages.
