A parasitic plant is a plant that derives its nutrients and water from another living plant or organism. There are several synonyms for parasitic plants, including hemiparasites, holoparasites, epiparasites, and mycoheterotrophs. Hemiparasites are plants that obtain some of their nutrients from their host plant but are also able to photosynthesize. Holoparasites, on the other hand, are completely dependent on their host for nutrients. Epiparasites grow on other plants but only use them for support, while mycoheterotrophs obtain their nutrients from fungi that themselves form a symbiotic relationship with other plants. Understanding these synonyms for parasitic plants is essential in understanding the wide variety of plants that depend on other organisms for their survival.
