Maize stem. Light micrograph of a section through the stem of a maize (corn, Zea mays) plant. The outer epidermis has a hypodermis of thick-walled cells of sclerenchyma (red). Next are two rings of supporting vascular bundles within the central parenchyma tissue (beige). Each vascular bundle is made up of surrounding thick-walled cells of supporting fibres - facing outwards is the phloem, and facing inwards to the stem is the xylem. Magnification: x13 when printed 10 centimetres wide.
