Conifer seeds are produced in tiny scale-like things called seed cones or ovulate cones. These are completely different from the yellow, wormlike, pollen-producing cones you shook next to your car. At pollination time, seed cones are so small and inconspicuous that most people never notice them.
Extending out from a central axis are microsporophylls (modified leaves). Under each microsporophyll is one or several microsporangia (pollen sacs). The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which, when fertilized by pollen, become seeds.The female cone structure varies more markedly between the different conifer families, and is often crucial for the identification of many species of conifers. cone (in formal botanical usage: strobilus, plural strobili) is an organ on plants in the division Pinophyta (conifers) that contains the reproductive structures. The familiar woody cone is the female cone, which produces seeds.
