Colour-enhanced Scanning Electron Micrograph (SEM) showing a celery stalk in cross section. A celery (Apium graveolens var. dulce) stalk is a special part of the leaf structure called a petiole. It serves many of the same functions as a stem. The pipes that conduct water and nutrients in a stalk of celery are shown in the micrograph. They contribute to the crunchiness of the stalks.
