Answer 2

Double fertilization triple fusion was discovered by Guignard and Nawaschin.

Explanation:

In the double fertilization process, two male gametes fertilize one female gamete to form zygote. Secondary nucleus forms zygote and endosperm respectively.

During this process, one of the two male gametes joins with the female gamete to form zygote which turns to seed and other male gamete fuses with the secondary nucleus to form triploid and primary endosperm nucleus which ends to the ultimate endosperm.
