Answer 2

Answer:

Two parasitic plants are mistletoe (Viscum album) and Rafflesia arnoldii.

Explanation:

Parasitic plants have certain modifications that make them suitable to obtain food and water from the host plants. They can be total parasites or hemiparasites. Mistletoe is a hemiparasite that grows on other trees or shrubs. They are green and can photosynthesize their own food.  

They have special structures called haustoria through which they obtain ‘water and nutrients’ from the host plant. Rafflesia is a total parasite that grows on the ground in the rainforests of Southeast Asia. The haustoria of these plants invade the roots of vines and all vegetative growth of Rafflesia occurs inside its host. Only the flowers grow on the surface.
