Parasitic roots:

  • Found in non-green parasitic plants.
  • Parasitic plants cannot make their own food and obtain food from the host.
  • These plants have no chlorophyll necessary for photosynthesis
  • Dependent on chlorophyll-bearing plants for their required food materials.
  • Adventitious roots from the nodes of these plants penetrate into the host tissue (via peg-like projections called haustoria) and enter into its conducting tissue (water-conducting and food-conducting) to acquire their nutrition.
  • Examples: Cuscuta, pinedrops, dodders, broomrapes, Pedicularis densiflora (commonly known as Indian warrior, a root parasite) and mistletoes (a hemiparasitic plants)
