microsporangium
pollen grains are the powdery pollens in the pollen sacs . Pollen sacs are situated in the anther. For a pistil to develop into a fruit and ovules to mature into seeds, pollen grains must be transfered from anthers to the stigma. This process is called pollination.

These air sacs make it easier to be carried by the wind
When bees are collecting pollen, the grains stick to specialized hairs around the knee joint of their hind legs, forming sacs. After an hour of collecting a build up of pollen grains, usually yellowish in color, is quite visible on the hind legs. The fuzzy hairs, stickiness of the pollen and electrostatic electricity contribute to the build up of these sacs.
Pine tree pollen is a "Necessaleb Brotusk", (a recessive type of pollen.) it comes from the bructus (the buds.) The bructus bossoms, creating a flowering bud.
