Euglenoids are unicellular flagellated protists. Their cell wall does not contain cellulose. The body is covered by thin and flexible pellicle. The pellicle is composed of fibrous elastin protein, small amount of lipid or/and carbohydrate. The euglenoids have two flagella, usually one long and one short. They are photosynthetic in the presence of sunlight. In dark even photosynthetic forms can behave like heterotrophs, predating on smaller organisms (holozoic) or feeding on organic remains (saprobic).
