The parasitic plant Cuscuta pentagona (dodder) grows by wrapping around a host plant, using specialized organs called haustoria to penetrate the host's stem and extract nutrients. Cuscuta lacks green leaves and is non-photosynthetic.
Explain one difference in the sub-cellular structures found in a stem cell from Cuscuta pentagona and those found in a stem cell from a typical photosynthetic host plant.
