There are some errors in here, the Tube nucleus in the pollen grain controls the growth of the pollen tube before disintegration.

It is the generative nucleus which consists of the two male nuclei. One of these fuses with the polar nucleus to form the triploid endosperm tissues which will become the endosperm and the other fuses with the oosphere to divide by mitosis to become the embryo.
