Gemmules are internal
sponges and are involved in asexual reproduction
. It is an asexually reproduced mass of cells, that is capable of developing into a new organism i.e., an adult sponge.
Role in asexual reproduction
Asexual reproduction in sponges occurs via budding, either by external or internal buds. The internal buds are called gemmules.[1] Only endogenous types of buds develop into new sponges.
Characteristics
Gemmules are resistant to
amoebocytes surrounded by a layer of spicules
and can survive conditions that would kill adult sponges. When the environment becomes less hostile, the gemmule resumes growing.
