4. One fuses with the egg and other fuses with central cell nuclei.

Correct answer: One fuses with the egg and other fuses with central cell nuclei.

In flowering plants, the two male gametes released into the embryo sac take part in double fertilization. One fuses with the egg to form the zygote, while the other fuses with the central cell nuclei to form the endosperm precursor.
