Fern rhizome, light micrograph. Transverse section through the central portion of the underground stem (rhizome) of the bracken fern (Pteridium aquilinum). The outer epidermis (black) covers a thin cortex layer (white) with parenchyma cells (green) below that. In the centre of the stem are vascular strands (oval-round) called meristeles. These include wood cells (xylem, red). The cells (black) between the meristeles are fibrous supporting tissue. Magnification: x11 when printed at 10 centimetres wide.
