Question

Asexual reproduction in sponges takes place with help of

• A. Multiple fission
• B. Binary fission
• C. Gemmule formation
• D. Gemmae

Answer 1

The correct option is C Gemmule formation

A. In multiple fission, the nucleus first divides by mitosis to form many nuclei and then the cytoplasm divides according to the number of nuclei. This kind of asexual reproduction is found in some protozoans.

B. In binary fission, parent cells divides into two identical daughter cells by mitosis. This kind of asexual reproduction is found in Amoeba.

C. Gemmules are the asexual reproductive bodies which are formed by endogenous budding in all freshwater and some marine sponges.

D. Gemmae are the asexual reproductive bodies that detach from the parent organism and develop into a complete organism.

Hence asexual reproduction in sponges takes place with help of gemmule formation. Gemmae are found in Bryophytes like Marchantia.

So, the correct answer is 'Gemmule formation'.
