What are gemmules and buds ?name one organism each in which these are formed
Answers
Gemmules are the specialized asexual spores formed in sponges. It gives rise to a new individual. In Hydra, the cells divide rapidly at a specific site and develop as an outgrowth called a bud. These buds, while attached to the parent plant, develop into small individuals.
Gemmules
Asexual reproduction is mainly carried out by budding and also by gemmulation. 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, that is, an adult sponge. Example is Spongilla lacustris
Buds
Budding is a type of asexual reproduction. It is most commonly associated with bacteria and yeast, but some animal species reproduce via budding, too. A parent organism creates a bud from its own cells, which then form the basis of the offspring organism and develop into an organism resembling the parent.
