Summary: A group of unicellular flagellates of ancient eukaryotic lineage with unclear taxonomy. Classification differs depending on what characteristics are used. Some authorities consider them to be an order of PROTOZOA. For others, they are classed as ALGAE due to the presence of CHLOROPLASTS in some genera. However, the origin of the chloroplasts is in dispute and they are missing from many of the genera. Euglenida lack a CELL WALL but are covered by a proteinaceous flexible coat, the pellicle, that allows the cell to change shape.
