Answer:

The pollen tube begins to grow through the pistil, directed by the tube nucleus.

Step-by-step explanation:

After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule.
