What are parasitic plants? Parasitic plants attach and feed off other plants using a parasitic structure called a haustorium. The haustorium is a specialised multicellular organ homologous to a root, which penetrates a host, makes a vascular connection, and facilitates the transfer of nutrients and other molecules.

Do parasites have roots?

All parasitic plants have modified roots, called haustoria, which penetrate the host plant, connecting them to the conductive system – either the xylem, the phloem, or both. For example, plants like Striga or Rhinanthus connect only to the xylem, via xylem bridges (xylem-feeding).
