What makes Pollen special.

Pollen contains the Microgametophytes, which create the male gametes of Seed Plants.  Pollen can also be transferred from plant to plant through a process called Pollination which includes traveling through the wind, or by hitching a ride on specific animals like Bees, Butterflies, and Humming Birds.  Pollen grains are equipped with a hard shell that protects the sperm cells during pollination and when they move from the Stamens located on the Pistils of all flowering pants, or from the male to the female cone parts of coniferous plants.  When pollen touches a suitable pistil or a female cone, it begins to germinate and create a pollen tube that is able to transfer sperm directly to the ovule.  Pollen grains are so small that you need a microscope to see them and their details, and the study of pollen is called Palynology, which is extremely useful in Paleoecology, Paleontology, Archeology, and even Forensic Science.
