Description
Light micrograph of a thin section through a deep red Zinnia elegans petal. The upper surface is completely covered with papillae, containing yellow chromoplasts and vacuoles filled with red Anthocyanin. In combination, these two coloring elements form the deep red colour of the petals to attract pollinators. Microscopic contrast method: Differential interference contrast. Magnification: x350 when printed at 10 centimetres wide.
