Hey what is that yellow stuff? AAACHOOOO !!

Have you noticed the dusting of yellow on all the cars, on everything?  Are you congested and perhaps sneezing more than normal?  It's probably pollen, a sign that Spring is here.  Check this out from Answers.com.

What is pollen? 
Plants produce microscopic round or oval pollen grains to reproduce. In some species, the plant uses the pollen from its own flowers to fertilize itself. Other types must be cross-pollinated; that is, in order for fertilization to take place and seeds to form, pollen must be transferred from the flower of one plant to that of another plant of the same species. Insects do this job for certain flowering plants, while other plants rely on wind transport; agents that effect pollination are also known as vectors.
