Parasitic Plants

bloodsucking ready A epenthetic plant is unmatched that derives close to or all of its sustenance from another plant. some 4,100 species in approximately 19 families of flowering plants ar known.[1] parasitical plants exact a modified root, the haustorium, that penetrates the host plant and connects to the xylem, phloem, or both. Classification Parasitic plants argon characterized as follows: * 1a. Obligate parazoan a leech that cannot over(p) its life bike without a host. * 1b. Facultative leech a parasite that can complete its life cycle independent of a host. * 2a. Stem parasite a parasite that attaches to the host groundwork. * 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 parasitic under graphic conditions and is also photosynthetic to some degree. Hemiparasites may just take hold water and mineral nutrients from the host plant. Many obtain at least partition of their organic nutrients from the host as well. For hemiparasites, single from each of the terzetto sets of terms can be use to the same species, e.g.

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