Question

Which one of the following derives nutrition from plants as a parasite
a)lice (b)cascuta (c) malaria parasite (d)bryophyllum

Answer 1

cascuta derives nutrition from plants as parasite.

Answer 2

Cuscuta is a parasitic plant, so it derives nutrition from plants because cuscuta has no chlorophyll content in it and also, it can't make its own through the process of photosynthesis.

Cuscuta grows on the other plants and uses their nutrition for its own growth which in turn weakens the host plant.

So option B is the right answer.
