gymnosperm Pine cone and exposed seeds of the pinyon pine (*Pinus edulis*). Pinyon pines are gymnosperms and bear their edible seeds, known as pine nuts, in protective cones instead of fruit.

Cones are essential reproductive structures in gymnosperms, serving as the sites where male and female gametophytes develop and where fertilization occurs. They are categorized into two types:1

Male Cones (Microstrobili): These structures contain microsporophylls, which bear microsporangia (pollen sacs). Inside these sacs, cells undergo meiotic division to produce microspores, which develop into pollen grains—the male gametophytes. These cones facilitate the release of pollen, which is then transported by wind or insects to the female cones.1
Female Ovulate Cones (Megastrobili): These cones consist of scales called megasporophylls that house megasporangia. Within these, a cell undergoes meiosis to produce megaspores, which develop into the female gametophyte. The female cone provides the environment for the ovule to be fertilized and for the subsequent development of the embryo and seed.12

By housing these specialized structures, cones ensure that pollen can be captured—often via a sticky "pollination droplet"—and that the resulting seeds are protected and nurtured until they are ready for dispersal.12
