The illustration shows a cross-section of a 2-year-old pine stem (Pinus L.). Pine is a genus of trees and shrubs in the family Pinaceae Lindl., comprising nearly 115 species, mostly growing in the temperate zone of the northern hemisphere. Pines are evergreen and characterized by a wide range of tolerance to environmental conditions and temperatures. The drawing shows the distribution of needles and wood, which is composed of vessels, fibers, and parenchyma. Pine seeds mature in hard, woody cones, and this genus includes species considered to be among the longest-living plants on Earth. Pines are an important source of timber, resin, essential oils, and edible seeds. Many species and varieties of pine are popular as ornamental plants, but some become invasive and threaten native flora.
