Reproduction in these protozoa generally occurs by fission, although sexual reproduction is observed in some species. Members of the group include the organisms that cause intestinal distress ( Giardia lamblia ) and sleeping sickness ( Trypanosoma brucei ) in humans. 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. For this reason, the organism is considered both a unicellular alga and a protozoan. Since it has the characteristics of both animals (motion) and plants (photosynthesis), many...
