How is the meeting of gametes in gymnosperms ensured?

The wind provides the meeting of gametes in gymnosperms.
In spring, small cones of two types are visible on young pine branches: male cones are greenish-yellow, gathered in tight groups at the bases of young shoots, and female cones are reddish, sitting alone on their tops.
On each scale of female cones, two ovules develop, in which female gametes (eggs) are located.
On the scales of male cones, two pollen sacs develop. Pollen ripens in them.
Ripe pollen spills out, and it is picked up by the wind, which can carry it over long distances.
If the pollen hits the female cones, pollination occurs. After that, the scales of the female cones are closed and glued together with resin.
