Question

Triple fusion means fusion of

• A. Two polar nuclei with male gamete
• B. Two eggs with male gametes
• C. Two male gametes and one egg
• D. Two male gametes and one egg and secondary nucleus

Answer 1

The correct option is A Two polar nuclei with male gamete

Triple fusion means fusion involving two polar nuclei in the embryo sac and a nucleus from the pollen grain that results in the formation of the endosperm. It is a peculiar characteristic in double fertilisation where diploid zygote and a triploid endosperm is formed.

So, the correct answer is option A.
