Caption: Light micrograph of a transverse section of the stem of an oak tree Quercus robur. The micrograph shows the xylem, the part of the vascular bundle which is responsible for the transportation of water and minerals. The xylem appears here as yellow holes. The fine red lines radiating outwards consist of cells of the horizontal xylem called rays. The rays distribute water radially to the cambium and also act as storage centres for starch and lipids. The cells in the roundish area at left are pith cells, a region of parenchymatous tissue located at the centre of the stem of many plants. Magnification: x7 at 35mm size.
