Now each pollen grain release two male gamates in the pollen tube. These male gamates travel through the pollen tube and reach the ovule.

When one male gamate fuse with egg then this process is known as Fertilization. And this type of process in plants is known as Syngamy...

When the male gamate fuse with two daughter nuclei then it is known as Triple fusion..
