Scots pine (Pinus sylvestris) stem. Light micrograph of a longitudinal section through a stem from a Scots pine tree. Right to left: epidermis (black) and cuticle (red) with developing cork; inner cortex and outer cortex of parenchyma cells (brown), containing starch grains; two resin canals and a line of parenchyma cells (light brown). Next, the secondary phloem, composed and sieve tube cells (dark brown); parenchyma cells, starch and albuminous cells. Next, secondary xylem (pink-red) of tracheids with bordered pits; horizontal ray of parenchyma cells and large simple pits (dark red); xylem of scattered resin canals lined with parenchyma cells (pink-brown). The pith (centre) consists of parenchyma cells. Magnification: x5 when printed 10 centimetres
