Question

Double fertilisation results in formation of

• A. Fruit
• B. Endosperm
• C. Seed
• D. Megaspore

Answer 1

The correct option is B Endosperm

Double fertilisation
The process involving two fusion events in which the two haploid male gametes released by the pollen tube fuse with the haploid egg cell and diploid central cell to form the zygote and primary endosperm cell respectively is referred to as double fertilisation. This is unique to angiosperms.

• Fusion of one male gamete with the egg cell is called syngamy
• Fusion of the other male gamete with the central cell containing the secondary nucleus (two fused polar nuclei) is called triple fusion

Syngamy and triple fusion together constitute the process of double fertilisation.


Final answer
(d) Endosperm
