The pollen tube extends
The pollen tube continues to grow into the ovary, which contains the ovule.
The car is out of control as it performs an oval-shaped doughnut trying to miss an aviary (ovary) containing fruit bats, but heads towards a mule (ovule) and a seed which are pulling a cart.
NOTE:
Ovary turns into a fruit
And Ovule turns into a seed
Example
Once the pollen tube has grown through the style it will continue to grow through the ovary until it enters the ovule of the flower.
