Early in their development female cones will open slightly to allow pollen to enter and fertilize , the cone will then close up until the seed is properly fertilized and ready. This process takes about three years. At that time the scales of the cone will open to release the seeds.
All seeds are equipped with a single wing (swipe for image) which creates a helicopter motion as it falls to the ground enabling the seed to travel further from underneath the shade of the parent tree. Increasing the chance of rooting and developing into a mighty pine tree.
Some seeds will stay in the pine cone when it falls to the ground. These seeds still have a chance of rooting with the help of animals like squirrels and woodpeckers, while feasting on the cone they will free and disperse the remaining seeds.

Pine trees like all conifers (trees that reproduce via seeds contained in cones vs in flowers )
possess both male and female cones on the same tree. The cones we are familiar with as displayed in the art are all female.
The male cones (also known as catkins) are present only during spring when they produce pollen. They are long thin structures (swipe for image )located on the lower branches of the tree, this is to prevent the pollen from falling on the female cones of the same tree, to promote fertilization with other pine trees, which enhances genetic variation among trees.
