उत्तर

After pollination a pollen grain has three haploid nuclei : one tube nucleus and two sperm nuclei.

Explanation:

The tube nucleus controls the growth of the pollen tube, while the two sperm nuclei participate in fertilization – one fuses with the egg to form the zygote and the other fuses with the polar nuclei to form the endosperm.
