Conifer seeds are produced in tiny scale-like things called seed cones or ovulate cones. These are completely different from the yellow, wormlike, pollen-producing cones you shook next to your car. At pollination time, seed cones are so small and inconspicuous that most people never notice them.
Pollen cones are much smaller than their woody seed cone counterparts; they are usually produced in clusters at the tips of the lower branches of a tree. Mount a small amount of conifer pollen in a drop of water on a slide, and examine it with the aid of your compound microscope..
