Some of these protozoa have only a single flagellum (for example, Trypanosoma ), but others may have up to eight (for example, Giardia ). Flagellar motion tends to be jerky, so flagellates can be identified in live specimens by this characteristic movement. Also in this group is Euglena gracilis , a flagellated organism that also has chlorophyll pigments for photosynthesis.
