Plants or Animals
Mesodinium chamaeleon, a strange green creature found in Denmark that lives at the bottom of the sea, is causing researchers to rethink traditional ways of classifying living organisms. Traditionally there is a difference between animals and plants: • Animals cannot produce their own energy and must eat other animals or plants to get energy for their survival. • Plants use photosynthesis to get energy from the sun for their survival. Chlorophyll is the green pigment in plant cells that enables photosynthesis to happen, and is one of the defining traits of plants. Mesodinium chamaeleon does both.
