Reproduction
Conifers produce their seeds inside a protective cone called a strobilus. Most species are monoecious, with male and female cones on the same tree. All conifers are wind-pollinated. In conifers such as pines, the cones are woody, and when mature the scales usually spread open allowing the seeds, which are often winged, to fall out and be dispersed by the wind. In others such as firs and cedars, the cones disintegrate to release the seeds.
