The answer is Euglena. Euglena is a genus of single-celled flagellate eukaryotes. It is a large genus of unicellular protists, which have both plant and animal characteristics. All are motile by means of a flagellum. Most have chloroplasts (alga and plant characteristic). Euglenids are believed to descend from an ancestor that took up green algae by secondary endosymbiosis.
