Question

what is the difference between syngamy and triple fusion?

Answer 1

Syngamy:

It is gametic fusion between the male gamete and the egg resulting in the formation of zygote. The zygote which develops to the embryo. In this fertilization two nuclei are involved resulting in the formation of diploid zygote.

Triple fusion:

It is the gametic fusion of one male gamete with the diploid secondary nucleus resulting in the formation of the triploid nucleus. The triple fusion results in the formation of the triploid tissue known as the endosperm. The endosperm nurtures their by helping in the growth and development of the embryo.
