In angiosperms, after pollenation occurs and a pollen tube forms, is the pollen still present on the stigma?

Question

Does the pollen grain stay on the tip of the pistil, or does it move down into the pistil's interior with the pollen tube?

Answer 1

There are three parts to a flowers pistil. The stigma, the style, and the ovary. First the pollen sticks to the stigma which is the very tip, that's where you are seeing the pollen stick to it. Then it goes down the style into the ovary. Not all the pollen goes down into the style.

Answer 2

The pollen tube grows from the grain deposited on the stigma of the female pistil carrying the tube nucleus and 2 sperm nuclei for double fertiliztion of the ovule. The grain opens up and is only the carrying vessel for the gametes. It stays outside on the stigma.
