Question

Gemmule formation in sponges is associated with

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

Answer 1

The correct option is B asexual reproduction

Gemmule is a type of dormant internal bud formed in sponges. They develop these structures to overcome unfavourable conditions. It is associated with asexual reproduction when conditions are favourable.

Parthenocarpy is the formation of fruits without fertilization.

Parthenogenesis is the formation of an organism from an ovum without fertilization. Seen in several invertebrates and some plants.

Sexual reproduction is the formation of the male and female gamete and their fusion to form a zygote.
