Question

Fusion of one male gamete with egg and other of the same pollen tube with two polar nuclei is

• A. Vegetative fertilisation
• B. Double fertilisation
• C. Triple fusion
• D. Parthenogenesis

Answer 1

The correct option is B Double fertilisation

Double fertilisation
Double fertilisation refers to the process involving two fertilisation events. Out of the two haploid male gametes released from the pollen tube in the embryo sac:

• One of these fuses with the haploid egg cell to form a diploid zygote. This fusion of gametes is known as syngamy.
• The other one fuses with the diploid central cell to form the triploid primary endosperm cell.

Final answer
(c) Double fertilisation
