What Are Examples of Flagellates?

Some examples of flagellates include trypanosomes and Giardia lamblia. Trypanosome is a parasite that causes sleeping sickness when it comes into contact with a human. Giardia lamblia is also a parasite, and it causes distress in the stomach and intestines.

Giardia lamblia is typically found in rivers and mountain streams. Other types of flagellates include dinoflagellates, commonly found as plankton in both fresh and salt water, and euglena, which is a free-living type of flagellate. The volvox variety of flagellate, on the other hand, is typically found in colony clusters.

To qualify as a flagellate, the organism must have a single-cell nucleus and possess at least one flagellum that is used for both movement and sensation. A large majority of flagellates possess a firm outer covering or a coating that resembles jelly. Reproduction for these organisms involves both sexual and asexual methods.

Organisms under this category can be further divided into two different groups: phytomastigophorea and zoomastigophorea. The former are flagellates that resemble plants, while the latter resemble animals. Phytomastigophorea flagellates are able to produce food using photosynthesis. Zoomastigophorea flagellates, on the other hand, are found in the digestive tracts of small bugs and are able to absorb nutrients from cellulose.
