Light micrograph of the root cap and apical meristem of the genus Lilium, commonly known as the lilly. These monocots comprises more than a 100 well-known species which can be found in temperate regions of the northern hemisphere. Here the dome-shaped structure at the tip of the stem is the shoot apical meristem. The cells of this meristem are small, dense staining and contain prominent nuclei. All tissues of the stem and leaves arise from this terminal meristem. Mag: x15 @ 35mm.
