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.

The cone.
Maybe bees, animals, squirrels, wind
They are wind-pollinated. The anthers will release the pollen when the conditions are right, (usually about 2pm West-USA time) when the day is at it's warmest and the air at it's driest. Pollen is not released when it rains as rain has a devastating affect on pollination - it simply wipes the pollen out of the sky.
a pine tree does not have leaves. it has pine needles that are about 1 to 2 inches long
it could be pollen from nearby plants. it could also be spores from fungi on the tree. it could also be dried sap from the tree
It is different because the reproduction is spread by the wind. The wind carries the pollen and the pollen fertilizes the seed.
Yes, all pine trees reproduce through seeds. Pine tree seeds are produced in the female pine cone, which is much, much larger and far more robust than the small, catkin-like male cone, which only produces pollen.
5 inches
plants can carry both the sperm and the egg cell, making technically both male and female. This means it just mixes its pollen and egg to create a seed, as opposed to two mammals having to mate to create a baby. Plants might use an outside force, however, to take the pollen to the egg to fertilize it and create a seed. This is where bees, wind, etc. come in. Bees take pollen from flowers and spread it. Wind can shake a pine tree, making it release pollen from pine cones when open (try shaking a pine tree when the pine cones are open, you see a big fog of pollen).
Yes, my son developed a horrible reash , hives and blisters from a Pine tree he climbed up at my girlfriends house. I brought him to the doctor who recognized it right away. He called him a tree hugger! I never would have guessed!
