Detailed explanation-1: -Pine cones only come from pine trees, although all conifers produce cones. Pine cones and pine trees belong to a group of plants called gymnosperms and date back to prehistoric times. Gymnosperms are a group of plants who have naked seeds, not enclosed in an ovary.

Detailed explanation-2: -Pine cones are the woody fruiting body and reproductive organ of pine trees. Once pollinated, the tree’s female cones develop as the seeds mature and are usually conical or round shaped.

Detailed explanation-3: -Conifers. Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones. Most coniferous trees are evergreen and are specially adapted to survive in areas with lots of snow.

Detailed explanation-4: -The chief economic value of pines is in the construction and paper-products industries, but they are also sources of turpentine, rosin, oils, and wood tars. Edible pine seeds, which are sold commercially as pine nuts, pignoli, piñons, or pinyons, are produced by several species.

Detailed explanation-5: -A conifer cone (in formal botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants.
