Answers (1)

The differences between syngamy and triple fusion are as follows: 

Syngamy    Triple fusion
It refers to the fusion of male gamete with female gamete i.e egg cell in angiosperms is called syngamy                                                                           It refers to the fusion of the second male gamete with the 2 polar nuclei of the central cell. Since, in this fusion, 2 polar nuclei and one sperm nuclei fuse, it is called triple fusion
The end product is a zygote which is a diploid structure  The end product is the primary endosperm nuclei which are triploid. 
Both male and female gametes are involved within the syngamy.  Only male gametes participate in the triple fusion.
