bloodsucking vegetation A epenthetic plant is hotshot that derives close to or all of its sustenance from another plant. close 4,100 species in approximately 19 families of flowering plants ar known.[1] leechlike plants exact a modified root, the haustorium, that penetrates the host plant and connects to the xylem, phloem, or both. Classification Parasitic plants are characterized as follows: * 1a. Obligate parazoan a leech that cannot terminate its life bike without a host. * 1b. Facultative quick study a parasite that can complete its life cycle independent of a host. * 2a. Stem parasite a parasite that attaches to the host fore. * 2b. Root parasite a parasite that attaches to the host root. Holoparasite Hyobanche sanguinea, Richtersfeld, Namaqualand, northern cape, South Africa * 3a. Holoparasite a plant that is completely parasitic on other plants and has virtually no chlorophyll. * 3b. Hemiparasite a plant that is parasi tic under intrinsic conditions and is also photosynthetic to some degree. Hemiparasites may just pay off water and mineral nutrients from the host plant. Many obtain at least partition of their organic nutrients from the host as well. For hemiparasites, unrivaled from each of the terzetto sets of terms can be apply to the same species, e.g.

* genus Nuytsia floribunda ( occidental Australian Christmas guide) is an obligate root hemiparasite. * Rhinanthus (e.g. scandalmongering rattle) is a facultative root hemiparasite. * Mistletoe is an obligate stem hemiparasite. Holoparasites are ever obligate so only cardinal terms are needed, e.g. * Dodder is a stem holop arasite. * Hydnora spp. are root holopa! rasites. Plants unremarkably considered holoparasites include broomrape, dodder, Rafflesia, and Hydnoraceae. Plants usually considered hemiparasites include Castilleja, mistletoe, Western Australian Christmas tree and yellow rattle. set germination Seed germination of parasitic plants occurs in a variety of ways.
