What do flagellates use their flagella for?
In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella are generally used for propulsion. They may also be used to create a current that brings in food. In most such organisms, one or more flagella are located at or near the anterior of the cell, e.g., Euglena.
What does flagellation mean in biology?
A flagellate pertains to any cell or organism (especially microscopic) that has one or more flagella. Certain organisms are flagellated in certain stages of their life cycle. The flagellum is one of the locomotory organelles that many single-celled eukaryotes utilize to propel themselves in an aquatic medium.
What advantages do flagellates have over amoebas?
Flagellates possess one advantage over their amoeboid relatives in that they can swim. Therefore, enabling them to invade and adapt to a wider range of environments unsuitable for other amoebae.
Are flagellates harmful to humans?
In humans and other mammals, several widespread diseases are caused by flagellates. Perhaps the most widespread is giardiasis caused by the intestinal parasite Giardia lamblia, with symptoms such as diarrhea (water and nutrient loss) and painful abdominal cramps.

Which is the best description of a flagellate?
See Article History. Alternative Title: Mastigophora. Flagellate, (subphylum Mastigophora), any of a group of protozoans, mostly uninucleate organisms, that possess, at some time in the life cycle, one to many flagella for locomotion and sensation.
What kind of structure is a flagellum in an organism?
(A flagellum is a hairlike structure capable of whiplike lashing movements that furnish locomotion.) Flagellate, (subphylum Mastigophora), any of a group of protozoans, mostly uninucleate organisms, that possess, at some time in the life cycle, one to many flagella for locomotion and sensation.
What is the structure of a flagellated protozoan?
The flagellated protozoans range from a simple oval cell with one or more flagella to the structural sophistication of the collared flagellates (choanoflagellates, supergroup Opisthokonta). The collared flagellates lack photosynthetic pigments and are therefore colourless. They have a single flagellum surrounded by a….
Where do you find flagellates in a pond?
They are found during start up when the sludge is young or after an upset, but will quickly predominate over the amoebae because they are more efficient feeders. They are often found in trickling filter, oxidation ponds, lagoons and activated sludge. Flagellates may have one or two flagella or whips for locomotion.
