Question

Internal and external budding

Answer 1

External budding occurs in hydra where regenerative cells are used for reproduction. In this case, bud develops as an outgrowth due to repeated cell division and when this bud matures, it gets detached from the parent body and develop as full organism.
Internal budding involves 2 daughter cells that are produced within the mother cell which is then consumed by the offspring before their separation. For example, Toxoplasma gondi.
​Gemmules are produced inside the body of the organisms and is capable to form an individual on arrival of favourable conditions.
