Parasites can be divided into : holoparasites and hemiparasites. Holoparasites are those which are dependent on their host for all of their requirements, while hemiparasites are those, which receive only a part of their nourishment from host. Holoparasites and hemiparasites are also known as complete and partial parasites, respectively. Sandal wood is partial root parasite, which synthesises its own food but is dependent on host's roots for water and inorganic nutrients. Mistletoe is partial stem parasite. Orobanche (Broomrope) is complete root parasite. Ganodenma, a fungus, is parasitic on hardwood.
