Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (/pɪˈnɒfɪtə, ˈpnftə/), also known as Coniferophyta (/ˌkɒnɪfəˈrɒfɪtə, ftə/) or Coniferae. The division contains a single extant classPinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedarsDouglas-firscypressesfirsjuniperskaurilarchespineshemlocksredwoodsspruces, and yews.[1] As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species.[citation needed][2]

Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere,[1] but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. The narrow conical shape of northern conifers, and their downward-drooping limbs, help them shed snow. Many of them seasonally alter their biochemistry to make them more resistant to freezing. While tropical rainforests have more biodiversity and turnover, the immense conifer forests of the world represent the largest terrestrial carbon sink. Conifers are of great economic value for softwood lumber and paper production.[1]
