during internal budding in spongilla ,, each arechocyte froms 1 spongilla or 1 gemmule which contains large number of archeocytes form 1 spongilla?
Dear student,
In case of endogenous or internal budding in spongilla, two daughter cells are formed inside the mother cell. Spongilla (fresh water sponges) show endogenous budding where buds are called as "Gemmules." These gemmules are the mass of undifferentiated cells called archaeocytes that is surrounded by a protective coat of amphidisc spicules. When the environmental conditions are favourable, archaeocytes come out of a gemmule through a micropyle and form a new sponge.
Each archaeocyte form a new sponge.
Hope this information clears your doubt.
Regards,
