How does lack of green color affect the nutrition of Cuscuta?
Answer and explanation
Correct answer: It cannot make food properly and depends on a host
The governing concept is parasitic nutrition and the role of chlorophyll. Green colour generally indicates chlorophyll, the pigment needed to capture light for photosynthesis. Cuscuta has little or no chlorophyll, so it cannot manufacture sufficient food from carbon dioxide and water. It obtains nutrients from a host plant through specialised absorbing structures. Thus option A is correct; the other choices mention increased photosynthesis or organs absent from plants.
