Why is Cuscuta called a parasitic plant?
Answer and explanation
Correct answer: Because it takes food from another plant
Parasitic nutrition means obtaining nourishment from a living host instead of preparing sufficient food independently. Cuscuta has very little or no chlorophyll, so it cannot carry out adequate photosynthesis. It develops special sucking structures called haustoria that penetrate the host plant and absorb water and nutrients. Therefore, option A is correct; the other options describe impossible or unrelated functions.
