AIIMS 2017 Botany Asexual Reproduction in Animals MCQ Question

Gemmule formation is a form of asexual reproduction primarily observed in sponges (Porifera), where specialized cells aggregate to form a resistant structure that can survive adverse environmental conditions. This process allows sponges to reproduce and disperse when conditions are favorable. In contrast, Paramecium reproduces mainly through binary fission, Hydra typically reproduces asexually via budding, and yeast primarily reproduces through budding as well, making gemmule formation unique to sponges.
