Caption

Golgi apparatus in a plant parenchyma cell (arum or voodoo lily, Sauromatum guttatum), coloured transmission electron micrograph (TEM). Stacks of cisternae and vesicles are present. 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. The Golgi apparatus is a cell organelle in all plant and animal cells. The apparatus consists of flattened membrane bound sacs located close to the endoplasmic reticulum. The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles. Depending on the contents these are despatched to one of three destinations: within the cell to lysosomes; to the cell plasma membrane; outside the cell. Magnification: x17,770 when shortest axis printed at 25.
