Edible species are Daucus carota (carrots), Apium graveolens (celery) and Pastinaca sativa (parsnip). This family is also famous for some poisonous species. Alkaloids are found in such individuals as Cicuta maculatat (water hemlock) and Conium maculatum (poison hemlock).

biennial that is closely related to garden carrots, but with a much reduced taproot. During the second year of growth, the plants produce stalks with white, flat-topped flowers.
Embryogenesis in plants can commence from cells other than the fertilized egg cell. Embryogenesis initiated from somatic cells in vitro is an attractive system for studying early embryonic stages when they are accessible to experimental manipulation.
During the induction phase, histological examination of cross sections of petiole ex-plants of Daucus carota in Gamborg medium with a concentration of 0.
Axial and radial transport and the accumulation of photoassimilates in carrot taproot were studied using C-14 labelling and autoradiography. Axial transport of the C-14 labelled assimilates inside the taproot was rapid and occurred mainly in the young phloem found in rows radiating from the cambium.

A variant, WCHlO5, expressing CHr in the callus, as well as in regenerated plantlets, was isolated from a cell line derived from a wild carrot plant. The plantlets regenerated from WCHIO5 are green, but do not produce normal, dissected leaves.
