Nutrients from other sources on host for survival ; son have no leaves. : depends: hola parasite: completely dependant on host; hacks into vascular system, hemiparasitic fully photosynthetic just host for water and minerals. : no chlorophyll, gets food from dead matter, like bacteria and fungi; convert organic food dead material for them or my chorrizahal cso take sugars from fungi that took.
