Is an organ of the pine tree containing its reproductive structures.
Pine cones are the reproductive organs of pine trees. The cones are either male or female. Most pine tree species have both sexes of cones on each tree. The male cones produce pollen and the female cones produce ovules. The pollen and ovules must come into contact to fertilize and produce the next generation Pinecone gives you a storefront, social discovery, buyer and revenue insights, customer management and an exquisite buyer + seller experience.  A cone (in formal botanical usage: strobilus, plural strobili) is an organ on plants in the division Pinophyta (conifers) that contains the reproductive structures. A pine cone covered in ice after an ice storm. Male cones of a pine A classic example of a Lebanese Cedar cone. Immature female pine cone Pollen cone of a Japanese Larch Pineapple gall on Sitka Spruce caused by Adelges abietis. Dozens of male cones (orange and flower-like) occur in a cluster; the female cone is still immature (olive green) Ad. After the male cones release their pollen, it travels by wind to the female pine cones. After pollination, the female cone takes one and a half to three years to mature. Fertilization, the fusion of the sperm in the pollen with the ovary in the female seed, takes place a year after pollination. Male cones are smaller, more herbaceous, and shorter lived. The male cone is usually no more than 2 inches (5 cm) long and lives for only a few months in the spring or the autumn, depending on the species of pine. It is covered with microsporangia, or pollen sacs. After it releases its pollen, it falls off the tree. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to species. Extending out from a central axis are microsporophylls (modified leaves). A pine cone covered in ice after an ice storm. Male cones of a pine A classic example of a Lebanese Cedar cone.

Pine trees are only one of the conifer, or cone-bearing, plants; others include cedars, firs, cypresses, and redwoods. Pine cones, like the reproductive organs of other conifers, come in male and female varieties. In most species of pine, male and female cones grow on the same tree. The trees of some species have cones predominantly of only one sex, with a few of the opposite sex. Pinus is a genus of trees with about 115 species. Male cones are smaller, more herbaceous, and shorter lived. The male cone is usually no more than 2 inches (5 cm) long and lives for only a few months in the spring or the autumn, depending on the species of pine. It is covered with microsporangia, or pollen sacs. After it releases its pollen, it falls off the tree. pine·cone. n. The cone of a pine tree. pine, pinecone-Pine, the tree, is from Latin pinus, from Indo-European pei-, resin; pinecones were originally called pineapples. See also related terms for pine. pinecone-the seed-producing cone of a pine tree. pine, pine tree, true pine-a coniferous tree. 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.
