Dodder

• The dodder plant develops pale yellow or orange stems that wrap thread-like tendrils around host plants. Modified roots called haustoria penetrate the tissues of host plants such as petunias or potatoes and suck out water and nutrients. While the dodder plant contains some chlorophyll in its buds, fruit and stems, it does not rely on the energy made through photosynthesis to live.
  
  

Chlamydomonas

• The single-celled chlamydomonas, a type of green algae, grows in the dark if supplied with a carbon source. Some mutations allow the algae to produce chlorophyll even in the dark.
