21 Μαρ 2024 · Gemmule Formation Examples. Gemmule formation is a method of asexual reproduction used by certain organisms like: Freshwater sponges (Porifera) Marine sponges, bryozoans (moss animals) Hydras (Cnidaria) Planarians (Platyhelminthes) Role of Gemmule in Sponge Reproduction
An asexually produced mass of cells, which are capable of developing into a new organism or into an adult freshwater sponge, is termed a Gemmule. They are small bud-like cells, which are formed by sponges to withstand unfavourable environmental conditions.
Gemmules are internal buds found in 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.
Gemmule formation occurs in freshwater by several sponges like Spongilia and some water species such as sea sponges, figuline ficus, and various other types of poriferans. The organisms give out gemmules, which further give birth to new sponges.
24 Ιουν 2024 · Formation of Gemmules [Click Here for Sample Questions] Gemmule is created by few genus of fresh sponges like Spongilla and a few marine species of Ficulina genus, ocean sponges, and different poriferans. Gemmule Formation starts with the aggregation of ameboid cell in sponges.
Definition. Gemmules are specialized asexual reproductive structures found in certain sponges, serving as a means for survival and dispersal. These structures can remain dormant in unfavorable conditions and can eventually develop into new sponge individuals when environmental conditions improve.
Gemmules – Formation: A gemmule is a small, compact mass of cells that is capable of regenerating a complete organism from a single gemmule. Gemmules are formed in response to environmental stress, such as a lack of food or oxygen.
