Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. [5] Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given off by host shoots or roots, respectively.
The stems of the parasite are tightly coiled around the host while other stems remain loosely coiled, allowing them to seek out other parts of the host or a new host. The plant flowers and is either pollinated by insects or, if necessary, is self-pollinated. The seeds are dispersed on the ground beneath the host to await future germination.
Cuscuta. Cuscuta (/ k ʌ s ˈ k juː t ə /), commonly known as dodder or amarbel, is a genus of over 201 species of yellow, orange, or red (rarely green) parasitic plants.Formerly treated as the only genus in the family Cuscutaceae, it now is accepted as belonging in the morning glory family, Convolvulaceae, on the basis of the work of the Angiosperm Phylogeny Group.

Some parasitic plants can locate their host plants by detecting chemicals in the air or soil given off by host shoots or roots, respectively. About 4,500 species of parasitic plant in approximately 20 families of flowering plants are known. [68] [70] Species within the Orobanchaceae (broomrapes) are among the most economically destructive of ...
This is an annual parasitic plant that may resemble fine strands of spaghetti or twine strewn across other species in its habitat. A mature plant of this species may fulfill all of its food and water needs from the host plant, but they rarely kill their host. [1] It is native to western United States and Baja California in Mexico.
Mistletoe species grow on a wide range of host trees, some of which experience side effects including reduced growth, stunting, and loss of infested outer branches. A heavy infestation may also kill the host plant. Viscum album successfully parasitizes more than 200 tree and shrub species. [citation needed]
Juvenile Meloidogynes parasites hatch from eggs as vermiform, second-stage juveniles (J2), the first moult having occurred within the egg. Newly hatched juveniles have a short free-living stage in the soil, in the rhizosphere of the host plants. They may reinvade the host plants of their parent or migrate through the soil to find a new host root.
Phoradendron tomentosum can adversely affect trees growing in urban environments as well as in forests. [6] Although mistletoe is photosynthetic, it is an obligate, semi parasitic evergreen plant that infects host plants to derive support, water, and essential elements.
