Light micrograph of parenchyma cells in a female cone of Pinus sp. (ls). The image presents parenchyma cells, with a thin and flexible cell wall, a well-differentiated nucleous and other cytoplasmic structures. The parenchyma cells form the iller?tissue in the soft parts of plants. They carry out metabolic functions: photosynthesis, synthesis and storage of organic products, secretion, aeration and wound repair. They also carry out a support function. The pine is a resinous and aromatic evergreen conifer tree of the genus Pinus, of the family Pinaceae. It is the most widespread genus of trees in the Northern Hemisphere. Some pine products include: timber, wood pulp, pine resin (rosin and turpentine), charcoal, carbon black (carcinogenic), fuel gases and edible seeds (pine nuts). It has a great importance in bioenergy (as a biomass), forestry and ecology. Field of view size: 370 x 550 痠 (0.015 x 0.022 in)
