Detailed explanation-1: -Syngamy is the fusion of one of the male gamete with the egg cell to produce a zygote while In triple fusion, second male gamete fuses with two polar nuclei to produce primary endosperm nucleus .

Detailed explanation-2: -Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation. The fusion process occurs in the embryo sac of the angiosperms.

Detailed explanation-3: -One male gamete fuses with the female gamete and the other fuses with the secondary nucleus. As two male gametes take part and fertilization and fertilization takes place twice, this process is called double fertilization. Since three gametes are involved it is called triple fusion.

Detailed explanation-4: -The main difference between double fertilization and triple fusion is that double fertilization is the fusion of the embryo sac with two sperm cells whereas triple fusion is the fusion of sperm nucleus with the two polar nuclei in the central cell of the embryo sac.
