Question

What happens to tube nucleus once it reaches the embryo sac?
please answer it's urgent​

Answer 1

The tube nucleus controls the growth of the pollen tube as grows down the style and into the ovary of a flower. Eventually it penetrates the micropyle of an ovule and releases its two sperm into the 8-nucleate embryo sac. During double fertilization, one sperm fuses with the egg nucleus to form a zygote.
