Parenchyma cell from a plant (arum or voodoo lily, Sauromatum guttatum), coloured transmission electron micrograph (TEM). Note the cell wall, nucleus with nucleolus, amyloplast with starch grains and mitochondria. This plant's inflorescences last for only a few hours to a day and give off an unpleasant smell. The inflorescence disperses its odour by heating up. Beetle pollinators visit the flower due to the smell. Magnification: x880 when shortest axis printed at 25 millimetres.
