Vedclass · Answer

(C) Parasitic plants like $Orobanche$ (broomrape) are obligate root parasites. Their seeds require specific chemical signals to break dormancy and germinate. These seeds germinate only in the presence of specific chemical exudates (such as strigolactones) released by the roots of the host plant. This mechanism ensures that the parasite germinates only when a suitable host is nearby,increasing its chances of survival.
