Let me share with you a difference between gemmules and buds.

 

AspectGemmulesBuds
IntroductionGemmules are asexual reproductive structures formed by sponges, often for survival during adverse conditionsBuds are outgrowths or small projections on the parent organism which are capable of developing into a new individual
Formed byFormed by some freshwater and marine spongesFormed by various organisms, including plants, animals and fungi
StructureSmall, specialized cells encapsulated in a protective coatingOutgrowths containing differentiated tissues
Cell typesContains aggregated cells, including archaeocytes (sponge cells with totipotent capabilities)Contains differentiated cells, potentially representing various tissues depending on the organism
PurposePrimarily a survival strategy during unfavorable conditions, such as drought or freezingA means of asexual reproduction, allowing for the formation of genetically identical offspring
Release mechanismReleased into the environment when conditions improveMay remain attached to the parent organism or detach to form an independent individual
DevelopmentArchaeocytes within the gemmule can differentiate into various cell typesBuds have the potential to differentiate into a complete organism with organs and structures
Examples

 

 

·        Freshwater sponges

 

 

·        Hydra (a freshwater cnidarian)

·        yeast (a fungus)

·        Plants like potatoes (via tuber buds)
