Conifer Life Cycle Basics
Captions available
The idea
A conifer bears separate pollen cones and seed cones on one tree; wind carries pollen to the seed cone, where fertilization occurs.
In practice
Pine pollen released in spring drifts on wind currents until some grains land near an ovule inside a receptive cone.
Where people slip
Wind pollination is inefficient by design — a conifer compensates by releasing far more pollen than an insect-pollinated plant needs.
