Is a celery a monocot or dicot?

Celery, Apium graveolens, is a dicot. It is in the parsley family (Apiaceae or Umbeliferae), along with other notable dicots like the carrot. It has several characteristic features of a dicot, including vascular bundles in a ring around the center of the stem, or pith, flower parts in 5's, a prominent taproot, and leaves with a branching network of veins. Celery is commonly mislabeled as a monocot, though the reason for the misunderstanding is unclear.
