Question

Gemmule formation in sponges is useful in

• A. parthenogenesis
  
• B. asexual reproduction
  
• C. sexual reproduction
  
• D. parthenocarpy
  

Answer 1

The correct option is B asexual reproduction


Gemmules

Gemmules are the internal buds in sponges. Gemmule formation is the asexual method of reproduction. These are expelled from the adult sponges and are capable of developing into a new organism.


Sexual reproduction

Sexual reproduction involves the fusion of the gametes from two parents of opposite sex to form a zygote which develops into a new individual.

Parthenogenesis

Parthenogenesis is the development of the embryo without fertilisation like in the case of honey bees.

Parthenocarpy

Parthenocarpy is the production of fruits without fertilisation of ovules. It results in the production of seedless fruits, like in banana.

Final answer:

(a) Asexual reproduction
