what is a pinecone
A pine cone is an organ of the pine tree containing its reproductive structures. 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.ale 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.
