Mistletoe is a plant parasite that lives on the stems of other plants. It survives by removing water and assimilates from the host plant.
The mistletoe binds to the stem of the host plant and grows a specialised root-like tissue called a haustorium that attaches to different tissues in the stem.
One species of mistletoe, Viscum minimum, contains no chloroplasts.
Which of the options, A to D, explains why V. minimum does not need chloroplasts?
the haustorium of V. minimum attaches to sieve tube elements
the haustorium of V. minimum attaches to xylem vessels
the haustorium of V. minimum attaches to meristem cells
the haustorium of V. minimum attaches to cambium tissue
