In this study, the parasite in the roots makes the plant send extra sugars to the roots, thus costing the plants valuable resources.
In order to survive and acquire the nutrients necessary for its existence, in addition to rich soil, the plant undergoes the process of photosynthesis. Parasitic plants, also known as holoparasites, do not. They need other plants for their survival, their leaves being either null or reduced to small yellowish scales. Parasitic plants developed suction organs that penetrate the conductive bundles of the host plant.
