Yep! Pollen are haploid, but technically they’re actually monoploid (or equivalent, depending on polyploidy) given they’re a fully functioning organism.
This is surprisingly common. All the pollen, male bees and ants (and actually a bunch of males in the order Hymenoptera grow from unfertilized eggs), and algae, for example. Certain fungi go through most of their lifecycles haploid and have a brief diploid phase, which undergoes meiosis to get right back to haploid, albeit for gametes this time. Tons of stuff! Nature is fucking wild.

Edit: haha, I just saw my Dad pun.
Wait so then what happens when it combines with the sternum(?)?
Do you mean the pistil? The stamen is the part of a flower that creates pollen.
Assuming yes, it grows a tube down the pistil into the ovary, then sends sperm to fertilize the flower’s ovules.
